The flow_dissector feature in the Linux kernel 4.3 through 5.x before
5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This
occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit
hashrnd value as a secret, and because jhash (instead of siphash) is used.
The hashrnd value remains the same starting from boot time, and can be
inferred by an attacker. This affects net/core/flow_dissector.c and related
code.

"description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5437 advisory.\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. (CVE-2020-24394)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. (CVE-2020-10769)\n\n - A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14385)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.

This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6. (CVE-2019-18805)\n\n - A memory leak in the mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka CID-c8c2a057fdc7. (CVE-2019-19045)\n\n - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)\n\n - A memory leak in the bnxt_re_create_srq() function in drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copy to udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)\n\n - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid- axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c, drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c, drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid- microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid- tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)\n\n - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)\n\n - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub- buffer). (CVE-2019-19768)\n\n - A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.\n (CVE-2019-8980)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.\n (CVE-2020-10711)\n\n - In the Linux kernel through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur. (CVE-2020-11884)\n\n - An issue was discovered in the Linux kernel before 5.6.5. There is a use-after-free in block/bfq-iosched.c related to bfq_idle_slice_timer_body. (CVE-2020-12657)\n\n - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest.

In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.(CVE-2019-20811)\n\n - A flaw was found in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.(CVE-2020-10768)\n\n - A flaw was found in the Linux kernel's implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.(CVE-2020-10767)\n\n - A logic bug flaw was found in the Linux kernel's implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this vulnerability is to confidentiality.(CVE-2020-10766)\n\n - A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU.

This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker.

There is a NULL pointer\n dereference in tw5864_handle_frame() in\n drivers/media/pci/tw5864/tw5864-video.c, which may\n cause denial of service, aka\n CID-2e7682ebfc75.(CVE-2019-20806)A flaw was found in\n the ZRAM kernel module, where a user with a local\n account and the ability to read the\n /sys/class/zram-control/hot_add file can create ZRAM\n device nodes in the /dev/ directory. This read\n allocates kernel memory and is not accounted for a user\n that triggers the creation of that ZRAM device. With\n this vulnerability, continually reading the device may\n consume a large amount of system memory and cause the\n Out-of-Memory (OOM) killer to activate and terminate\n random userspace processes, possibly making the system\n inoperable.(CVE-2020-10781)In the Linux kernel before\n 5.4.16, a race condition in tty->disc_data handling in\n the slip and slcan line discipline could lead to a\n use-after-free, aka CID-0ace17d56824. This affects\n drivers/ net/slip/slip.c and drivers/\n net/can/slcan.c.(CVE-2020-14416)The VFIO PCI driver in\n the Linux kernel through 5.6.13 mishandles attempts to\n access disabled memory space.(CVE-2020-12888)The\n flow_dissector feature in the Linux kernel 4.3 through\n 5.x before 5.3.10 has a device tracking vulnerability,\n aka CID-55667441c84f. This occurs because the auto\n flowlabel of a UDP IPv6 packet relies on a 32-bit\n hashrnd value as a secret, and because jhash (instead\n of siphash) is used. The hashrnd value remains the same\n starting from boot time, and can be inferred by an\n attacker. This affects net/core/flow_dissector.c and\n related code.(CVE-2019-18282)In the Linux kernel\n through 5.7.6, usbtest_disconnect in\n drivers/usb/misc/usbtest.c has a memory leak, aka\n CID-28ebeb8db770.(CVE-2020-15393)An issue was\n discovered in the Linux kernel before 5.0.6.

This could lead to local\n information disclosure with system execution privileges\n needed. User interaction is not needed for\n exploitation.(CVE-2019-9445)A flaw was found in the\n Linux kernel's implementation of Userspace core dumps.\n This flaw allows an attacker with a local account to\n crash a trivial program and exfiltrate private kernel\n data.(CVE-2020-10732)go7007_snd_init in\n drivers/media/usb/go7007/snd-go7007.c in the Linux\n kernel before 5.6 does not call snd_card_free for a\n failure path, which causes a memory leak, aka\n CID-9453264ef586.(CVE-2019-20810)Legacy pairing and\n secure-connections pairing authentication in Bluetooth(r)\n BR/EDR Core Specification v5.2 and earlier may allow an\n unauthenticated user to complete authentication without\n pairing credentials via adjacent access. An\n unauthenticated, adjacent attacker could impersonate a\n Bluetooth BR/EDR master or slave to pair with a\n previously paired remote device to successfully\n complete the authentication procedure without knowing\n the link key.(CVE-2020-10135)An issue was discovered in\n the Linux kernel before 5.4.7. The\n prb_calc_retire_blk_tmo() function in\n net/packet/af_packet.c can result in a denial of\n service (CPU consumption and soft lockup) in a certain\n failure case involving TPACKET_V3, aka\n CID-b43d1f9f7067.(CVE-2019-20812)An issue was\n discovered in the Linux kernel through 5.7.1.\n drivers/tty/vt/keyboard.c has an integer overflow if\n k_ascii is called several times in a row, aka\n CID-b86dab054059. NOTE: Members in the community argue\n that the integer overflow does not lead to a security\n issue in this case.(CVE-2020-13974)In calc_vm_may_flags\n of ashmem.c, there is a possible arbitrary write to\n shared memory due to a permissions bypass. This could\n lead to local escalation of privilege by corrupting\n memory shared between processes, with no additional\n execution privileges needed. User interaction is not\n needed for exploitation. Product: Android Versions:\n Android kernel Android ID: A-142938932(CVE-2020-0009)A\n flaw was found in the Linux Kernel in versions after\n 4.5-rc1 in the way mremap handled DAX Huge Pages.

This\n call incorrectly reports it as being 'force disabled'\n when it is not and opens the system to Spectre v2\n attacks. The highest threat from this vulnerability is\n to confidentiality.(CVE-2020-10768)A flaw was found in\n the Linux kernel's implementation of the Enhanced IBPB\n (Indirect Branch Prediction Barrier). The IBPB\n mitigation will be disabled when STIBP is not available\n or when the Enhanced Indirect Branch Restricted\n Speculation (IBRS) is available. This flaw allows a\n local attacker to perform a Spectre V2 style attack\n when this configuration is active. The highest threat\n from this vulnerability is to\n confidentiality.(CVE-2020-10767)A logic bug flaw was\n found in the Linux kernel's implementation of SSBD. A\n bug in the logic handling allows an attacker with a\n local account to disable SSBD protection during a\n context switch when additional speculative execution\n mitigations are in place. This issue was introduced\n when the per task/process conditional STIPB switching\n was added on top of the existing SSBD switching.

The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)\n\n - The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially- crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.\n (CVE-2019-9500)\n\n - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.\n More typically, this vulnerability will result in denial-of-service conditions.

(CVE-2020-11668)\n\n - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA. (CVE-2019-14897)\n\n - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)\n\n - In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9. This affects drivers/usb/core/file.c. (CVE-2019-19537)\n\n - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. (CVE-2019-20636)\n\n - An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.\n This will cause a denial of service. (CVE-2019-12819)\n\n - Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e. (CVE-2019-19057)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.\n (CVE-2019-14896)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka CID-4ea99936a163. (CVE-2019-19767)\n\n - Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e.

(CVE-2020-14803)\n\n - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field.\n (CVE-2020-15436)\n\n - Net-SNMP through 5.7.3 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. (CVE-2020-15862)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. (CVE-2020-24394)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack- based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \\x00\\x04\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.\n (CVE-2020-29573)\n\n - A flaw incorrect umask during file or directory modification in the Linux kernel NFS (network file system) functionality was found in the way user create and delete object using NFSv4.2 or newer if both simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with access to the NFS could use this flaw to starve the resources causing denial of service. (CVE-2020-35513)\n\n - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS- TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11, and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.\n Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)\n\n - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request.\n (CVE-2021-25122)\n\n - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. (CVE-2021-25329)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command without authentication. Successful exploitation of this flaw could lead to privilege escalation.

All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected\n 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new\n filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the\n current umask is not considered. (CVE-2020-24394)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers\n to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c\n instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption\n and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause\n the system to crash or cause a denial of service. The highest threat from this vulnerability is to data\n confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-\n based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with\n a non-canonical bit pattern, as seen when passing a \\x00\\x04\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x04 value to\n sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because\n of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,\n the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.\n (CVE-2020-29573)\n\n - A flaw incorrect umask during file or directory modification in the Linux kernel NFS (network file system)\n functionality was found in the way user create and delete object using NFSv4.2 or newer if both\n simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with access to\n the NFS could use this flaw to starve the resources causing denial of service. (CVE-2020-35513)\n\n - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG\n features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,\n but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or\n tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-\n TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server\n environments that combine BIND servers with Active Directory domain controllers. The most likely outcome\n of a successful exploitation of the vulnerability is a crash of the named process. However, remote code\n execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,\n and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.\n Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)\n\n - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to\n 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one\n request to another meaning user A and user B could both see the results of user A's request.\n (CVE-2021-25122)\n\n - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to\n 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be\n used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published\n prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to\n this issue. (CVE-2021-25329)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which\n allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single\n backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is\n exploitable by any local user who can execute the sudo command without authentication. Successful\n exploitation of this flaw could lead to privilege escalation. (CVE-2021-3156)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n # https://portal.nutanix.com/page/documents/security-advisories/release-advisories/details?id=NXSA-AOS-5.19.2\n script_set_attribute(attribute:\"see_also\", value:\"http://www.nessus.org/u?dcf02d8b\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the Nutanix AOS software to recommended version.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:M/Au:S/C:P/I:P/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:H/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:H/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2020-25643\");\n script_set_attribute(attribute:\"cvss3_score_source\", value:\"CVE-2020-10878\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n script_set_attribute(attribute:\"exploit_framework_core\", value:\"true\");\n script_set_attribute(attribute:\"exploited_by_malware\", value:\"true\");\n script_set_attribute(attribute:\"metasploit_name\", value:'Sudo Heap-Based Buffer Overflow');\n script_set_attribute(attribute:\"exploit_framework_metasploit\", value:\"true\");\n script_set_attribute(attribute:\"exploit_framework_canvas\", value:\"true\");\n script_set_attribute(attribute:\"canvas_package\", value:\"CANVAS\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2020/01/16\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2022/08/24\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2022/09/01\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:nutanix:aos\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Misc.\");\n\n script_copyright(english:\"This script is Copyright (C) 2022-2023 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"nutanix_collect.nasl\");\n script_require_keys(\"Host/Nutanix/Data/lts\", \"Host/Nutanix/Data/Service\", \"Host/Nutanix/Data/Version\", \"Host/Nutanix/Data/arch\");\n\n exit(0);\n}\n\ninclude('vcf.inc');\ninclude('vcf_extras.inc');\n\nvar app_info = vcf::nutanix::get_app_info();\n\nvar constraints = [\n { 'fixed_version' : '5.19.2', 'product' : 'AOS', 'fixed_display' : 'Upgrade the AOS install to 5.19.2 or higher.', 'lts' : FALSE },\n { 'fixed_version' : '5.19.2', 'product' : 'NDFS', 'fixed_display' : 'Upgrade the AOS install to 5.19.2 or higher.', 'lts' : FALSE }\n];\n\nvcf::nutanix::check_version_and_report(app_info:app_info, constraints:constraints, severity:SECURITY_HOLE);\n", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2023-05-18T15:23:34", "description": "The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2020:1769 advisory.\n\n -

"According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc. Security Fix(es):In uvc_scan_chain_forward of uvc_driver.c, there is a possible linked list corruption due to an unusual root cause. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID:\n A-111893654References: Upstream kernel.(CVE-2020-0404)A flaw was found in the Linux kernel in versions from 2.2.3 through 5.9.rc5. When changing screen size, an out-of-bounds memory write can occur leading to memory corruption or a denial of service. This highest threat from this vulnerability is to system availability.(CVE-2020-14390)A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs4proc.c instead of fsfs4xdr.c, aka CID-b4487b935452.(CVE-2020-25212)A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service.\n The highest threat from this vulnerability is to system availability.(CVE-2020-14385)In the Linux kernel before 5.7.8, fsfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131.\n This occurs because the current umask is not considered.(CVE-2020-24394)The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe.(CVE-2020-25284)An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys et/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.(CVE-2019-18805)Insufficient input validation in i40e driver for Intel(R) Ethernet 700 Series Controllers versions before 7.0 may allow an authenticated user to potentially enable a denial of service via local access.(CVE-2019-0147)Buffer overflow in i40e driver for Intel(R) Ethernet 700 Series Controllers versions before 7.0 may allow an authenticated user to potentially enable an escalation of privilege via local access.(CVE-2020-0145)A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.(CVE-2020-25285)A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing.

(CVE-2020-14803)\n\n - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field.\n (CVE-2020-15436)\n\n - Net-SNMP through 5.7.3 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. (CVE-2020-15862)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. (CVE-2020-24394)\n\n - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.\n (CVE-2020-25211)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-25645)\n\n - A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of bounds. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25656)\n\n - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that relies on UDP source port randomization are indirectly affected as well on the Linux Based Products (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4, SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7 LTE EU: Version (CVE-2020-25705)\n\n - In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore. (CVE-2020-28374)\n\n - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack- based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \\x00\\x04\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.\n (CVE-2020-29573)\n\n - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.\n (CVE-2020-29661)\n\n - A flaw incorrect umask during file or directory modification in the Linux kernel NFS (network file system) functionality was found in the way user create and delete object using NFSv4.2 or newer if both simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with access to the NFS could use this flaw to starve the resources causing denial of service. (CVE-2020-35513)\n\n - In the Linux kernel 4.14 longterm through 4.14.165 and 4.19 longterm through 4.19.96 (and 5.x before 5.2), there is a use-after-free (write) in the i915_ppgtt_close function in drivers/gpu/drm/i915/i915_gem_gtt.c, aka CID-7dc40713618c. This is related to i915_gem_context_destroy_ioctl in drivers/gpu/drm/i915/i915_gem_context.c. (CVE-2020-7053)\n\n - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS- TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11, and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.\n Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)\n\n - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system availability.\n (CVE-2021-20265)\n\n - A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-20305)\n\n - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries).

When an iSCSI transport is registered with the iSCSI subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)\n\n - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)\n\n - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message. (CVE-2021-27365)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command without authentication. Successful exploitation of this flaw could lead to privilege escalation.

(CVE-2020-15862)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name\n types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different\n instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both\n GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a\n possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)\n Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in\n an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp\n authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an\n attacker can control both items being compared then that attacker could trigger a crash. For example if\n the attacker can trick a client or server into checking a malicious certificate against a malicious CRL\n then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a\n certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements\n automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an\n unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of\n EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will\n accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected\n 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w).

(CVE-2020-24394)\n\n - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could\n overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in\n ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.\n (CVE-2020-25211)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers\n to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c\n instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption\n and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause\n the system to crash or cause a denial of service. The highest threat from this vulnerability is to data\n confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may\n be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE\n tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from\n this vulnerability is to data confidentiality. (CVE-2020-25645)\n\n - A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was\n using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of\n bounds. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25656)\n\n - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports.

This is related to i915_gem_context_destroy_ioctl in\n drivers/gpu/drm/i915/i915_gem_context.c. (CVE-2020-7053)\n\n - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG\n features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,\n but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or\n tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-\n TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server\n environments that combine BIND servers with Active Directory domain controllers. The most likely outcome\n of a successful exploitation of the vulnerability is a crash of the named process. However, remote code\n execution, while unproven, is theoretically possible.

(CVE-2021-2163)\n\n - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to\n 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one\n request to another meaning user A and user B could both see the results of user A's request.\n (CVE-2021-25122)\n\n - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->\n 9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND\n 9.17 development branch, when a vulnerable version of named receives a query for a record triggering the\n flaw described above, the named process will terminate due to a failed assertion check. The vulnerability\n affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other\n versions of BIND 9. (CVE-2021-25215)\n\n - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to\n 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be\n used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published\n prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to\n this issue. (CVE-2021-25329)\n\n - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write\n access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character\n sequence. (CVE-2021-26937)\n\n - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine\n the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI\n subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at\n /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in\n drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the\n pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)\n\n - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is\n adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)\n\n - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have\n appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can\n send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a\n Netlink message. (CVE-2021-27365)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which\n allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single\n backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is\n exploitable by any local user who can execute the sudo command without authentication. Successful\n exploitation of this flaw could lead to privilege escalation.

"description": "The version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.\n\n - libpng before 1.6.32 does not properly check the length of chunks against the user limit. (CVE-2017-12652)\n\n - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename. (CVE-2017-15715)\n\n - A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).\n (CVE-2017-18190)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0, disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)\n\n - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. (CVE-2018-1283)\n\n - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.\n (CVE-2018-1303)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). (CVE-2018-20843)\n\n - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL. (CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the victim must open a specially crafted chm file. The fixed version is: after commit 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. (CVE-2019-16994)\n\n - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length checks. In cases where the application calling the library did not perform a sanity check on the inputs it could result in a crash due to a buffer overflow. (CVE-2019-17006)\n\n - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. (CVE-2019-17053)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. (CVE-2019-17498)\n\n - In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed. (CVE-2019-18197)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time. (CVE-2019-19046)\n\n - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929.

(CVE-2020-15862)\n\n - Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. (CVE-2020-17527)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. (CVE-2020-1927)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. (CVE-2020-1934)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w).

(CVE-2020-8492)\n\n - In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.\n (CVE-2020-8622)\n\n - In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with\n --enable-native-pkcs11 * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker (CVE-2020-8623)\n\n - In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker who has been granted privileges to change a specific subset of the zone's content could abuse these unintended additional privileges to update other contents of the zone. (CVE-2020-8624)\n\n - cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.\n (CVE-2020-8631)\n\n - In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords. (CVE-2020-8632)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c. (CVE-2020-8647)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c. (CVE-2020-8649)\n\n - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. (CVE-2020-9383)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command without authentication. Successful exploitation of this flaw could lead to privilege escalation. (CVE-2021-3156)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2022-09-01T00:00:00",

(CVE-2017-12652)\n\n - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline\n character in a malicious filename, rather than matching only the end of the filename. This could be\n exploited in environments where uploads of some files are are externally blocked, but only by matching the\n trailing portion of the filename. (CVE-2017-15715)\n\n - A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows\n remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in\n conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither\n the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).\n (CVE-2017-18190)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an\n out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0,\n disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances\n created by cloning a golden master or template system, sharing ssh host keys, and being able to\n impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)\n\n - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI\n applications (SessionEnv on, not the default), a remote user may influence their content by using a\n Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data\n to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per\n CGI specifications. (CVE-2018-1283)\n\n - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30\n due to an out of bound read while preparing data to be cached in shared memory. It could be used as a\n Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk\n since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.\n (CVE-2018-1303)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()\n and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons\n could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be\n usable for denial-of-service attacks). (CVE-2018-20843)\n\n - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be\n self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the\n request URL. (CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component\n is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the\n victim must open a specially crafted chm file. The fixed version is: after commit\n 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and\n xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a\n crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger\n an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information\n disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign\n CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in\n CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This\n vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited\n to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file\n permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux\n kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause\n a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical\n Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of\n symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only\n affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own\n home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to\n read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a\n cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent\n client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and\n send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A\n local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical\n interface, change the input method engine, or modify other input related configurations of the victim\n user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may\n contain files with permissions the attacker did not have or in paths he did not have access to. Extracting\n those archives from a high-privilege user without carefully reviewing them may lead to the compromise of\n the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a\n malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS\n expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to\n document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber)\n then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when\n hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has\n XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in\n Lib/xmlrpc/server.py in Python 3.x.

OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)\n Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in\n an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp\n authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an\n attacker can control both items being compared then that attacker could trigger a crash. For example if\n the attacker can trick a client or server into checking a malicious certificate against a malicious CRL\n then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a\n certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements\n automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an\n unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of\n EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will\n accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected\n 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new\n filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131.

(CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). This vulnerability affects Firefox < 71.

There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. (CVE-2019-16994)\n\n - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length checks. In cases where the application calling the library did not perform a sanity check on the inputs it could result in a crash due to a buffer overflow. (CVE-2019-17006)\n\n - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7.

(CVE-2019-17055)\n\n - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. (CVE-2019-17498)\n\n - In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed. (CVE-2019-18197)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time.

(CVE-2020-10751)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. (CVE-2020-10769)\n\n - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.\n (CVE-2020-10942)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash). (CVE-2020-12243)\n\n - When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.

This vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)\n\n - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.\n *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)\n\n - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest threat from this vulnerability is to confidentiality and system availability. (CVE-2020-12403)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.

(CVE-2020-14803)\n\n - Net-SNMP through 5.7.3 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. (CVE-2020-15862)\n\n - Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. (CVE-2020-17527)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. (CVE-2020-1927)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a malicious FTP server. (CVE-2020-1934)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w).

To be vulnerable, the system must: * be running BIND that was built with\n --enable-native-pkcs11 * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker (CVE-2020-8623)\n\n - In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker who has been granted privileges to change a specific subset of the zone's content could abuse these unintended additional privileges to update other contents of the zone. (CVE-2020-8624)\n\n - cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.\n (CVE-2020-8631)\n\n - In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords. (CVE-2020-8632)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c. (CVE-2020-8647)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c. (CVE-2020-8649)\n\n - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. (CVE-2020-9383)\n\n - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single backslash character. (CVE-2021-3156)\n\n - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command without authentication. Successful exploitation of this flaw could lead to privilege escalation.

(CVE-2017-12652)\n\n - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline\n character in a malicious filename, rather than matching only the end of the filename. This could be\n exploited in environments where uploads of some files are are externally blocked, but only by matching the\n trailing portion of the filename. (CVE-2017-15715)\n\n - A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows\n remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in\n conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither\n the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).\n (CVE-2017-18190)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an\n out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0,\n disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances\n created by cloning a golden master or template system, sharing ssh host keys, and being able to\n impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)\n\n - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI\n applications (SessionEnv on, not the default), a remote user may influence their content by using a\n Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data\n to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per\n CGI specifications. (CVE-2018-1283)\n\n - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30\n due to an out of bound read while preparing data to be cached in shared memory. It could be used as a\n Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk\n since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.\n (CVE-2018-1303)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()\n and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons\n could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be\n usable for denial-of-service attacks). (CVE-2018-20843)\n\n - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be\n self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the\n request URL. (CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component\n is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the\n victim must open a specially crafted chm file. The fixed version is: after commit\n 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and\n xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a\n crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger\n an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information\n disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign\n CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in\n CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This\n vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited\n to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file\n permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux\n kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause\n a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical\n Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of\n symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only\n affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own\n home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to\n read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a\n cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent\n client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and\n send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A\n local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical\n interface, change the input method engine, or modify other input related configurations of the victim\n user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may\n contain files with permissions the attacker did not have or in paths he did not have access to. Extracting\n those archives from a high-privilege user without carefully reviewing them may lead to the compromise of\n the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a\n malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS\n expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to\n document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber)\n then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when\n hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has\n XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in\n Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary\n JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when\n register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka\n CID-07f12b26e21a. (CVE-2019-16994)\n\n - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length\n checks. In cases where the application calling the library did not perform a sanity check on the inputs it\n could result in a crash due to a buffer overflow. (CVE-2019-17006)\n\n - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting\n in an invalid state transition in the TLS State Machine.

(CVE-2020-15999)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN\n and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't\n correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would\n allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this\n vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to\n 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on\n an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely\n lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak\n between requests.

(CVE-2020-1934)\n\n - The X.509 GeneralName type is a generic type for representing different types of names. One of those name\n types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different\n instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both\n GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a\n possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)\n Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in\n an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp\n authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an\n attacker can control both items being compared then that attacker could trigger a crash. For example if\n the attacker can trick a client or server into checking a malicious certificate against a malicious CRL\n then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a\n certificate. This checking happens prior to the signatures on the certificate and CRL being verified.\n OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements\n automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an\n unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of\n EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will\n accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.\n Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected\n 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new\n filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131.
