"exploitation": null, "vulnersScore": -0.1}, "sourceHref": "https://0day.today/exploit/32994", "sourceData": "Linux - Broken Permission and Object Lifetime Handling for PTRACE_TRACEME Exploit\r\n\r\n== Summary ==\r\nThis bug report describes two issues introduced by commit 64b875f7ac8a (\"ptrace:\r\nCapture the ptracer's creds not PT_PTRACE_CAP\", introduced in v4.10 but also\r\nstable-backported to older versions). I will send a suggested patch in a minute\r\n(\"ptrace: Fix ->ptracer_cred handling for PTRACE_TRACEME\").\r\n\r\nWhen called for PTRACE_TRACEME, ptrace_link() would obtain an RCU reference\r\nto the parent's objective credentials, then give that pointer to\r\nget_cred(). However, the object lifetime rules for things like struct cred\r\ndo not permit unconditionally turning an RCU reference into a stable\r\nreference.\r\n\r\nPTRACE_TRACEME records the parent's credentials as if the parent was acting\r\nas the subject, but that's not the case. If a malicious unprivileged child\r\nuses PTRACE_TRACEME and the parent is privileged, and at a later point, the\r\nparent process becomes attacker-controlled (because it drops privileges and\r\ncalls execve()), the attacker ends up with control over two processes with\r\na privileged ptrace relationship, which can be abused to ptrace a suid\r\nbinary and obtain root privileges.\r\n\r\n\r\n== Long bug description ==\r\nWhile I was trying to refactor the cred_guard_mutex logic, I stumbled over the\r\nfollowing issues:\r\n\r\nptrace relationships can be set up in two ways: Either the tracer attaches to\r\nanother process (PTRACE_ATTACH/PTRACE_SEIZE), or the tracee forces its parent to\r\nattach to it (PTRACE_TRACEME).\r\nWhen a tracee goes through a privilege-gaining execve(), the kernel checks\r\nwhether the ptrace relationship is privileged. If it is not, the\r\nprivilege-gaining effect of execve is suppressed.\r\nThe idea here is that a privileged tracer (e.g. if root runs \"strace\" on\r\nsome process) is allowed to trace through setuid/setcap execution, but an\r\nunprivileged tracer must not be allowed to do that, since it could otherwise\r\ninject arbitrary code into privileged processes.\r\n\r\nIn the PTRACE_ATTACH/PTRACE_SEIZE case, the tracer's credentials are recorded at\r\nthe time it calls PTRACE_ATTACH/PTRACE_SEIZE; later, when the tracee goes\r\nthrough execve(), it is checked whether the recorded credentials are capable\r\nover the tracee's user namespace.\r\nBut in the PTRACE_TRACEME case, the kernel also records _the tracer's_\r\ncredentials, even though the tracer is not requesting the operation. There are\r\ntwo problems with that.\r\n\r\n\r\nFirst, there is an object lifetime issue:\r\nptrace_traceme() -> ptrace_link() grabs __task_cred(new_parent) in an RCU\r\nread-side critical section, then passes the creds to __ptrace_link(), which\r\ncalls get_cred() on them.

task A: fork()s a child, task B\r\n - task B: fork()s a child, task C\r\n - task B: execve(/some/special/suid/binary)\r\n - task C: PTRACE_TRACEME (creates privileged ptrace relationship)\r\n - task C: execve(/usr/bin/passwd)\r\n - task B: drop privileges (setresuid(getuid(), getuid(), getuid()))\r\n - task B: become dumpable again (e.g. execve(/some/other/binary))\r\n - task A: PTRACE_ATTACH to task B\r\n - task A: use ptrace to take control of task B\r\n - task B: use ptrace to take control of task C\r\n\r\nPolkit's pkexec helper fits this pattern. On a typical desktop system, any\r\nprocess running under an active local session can invoke some helpers through\r\npkexec (see configuration in /usr/share/polkit-1/actions, search for <action>s\r\nthat specify <allow_active>yes</allow_active> and\r\n<annotate key=\"org.freedesktop.policykit.exec.path\">...</annotate>).\r\nWhile pkexec is normally used to run programs as root, pkexec actually allows\r\nits caller to specify the user to run a command as with --user, which permits\r\nusing pkexec to run a command as the user who executed pkexec. (Which is kinda\r\nweird... why would I want to run pkexec helpers as more than one fixed user?)\r\n\r\nI have attached a proof-of-concept that works on Debian 10 running a distro\r\nkernel and the XFCE desktop environment; if you use a different desktop\r\nenvironment, you may have to add a path to the `helpers` array in the PoC. When\r\nyou compile and run it in an active local session, you should get a root shell\r\nwithin a second.\r\n\r\n\r\nProof of Concept:\r\nhttps://github.com/offensive-security/exploitdb-bin-sploits/raw/master/bin-sploits/47133.zip\n\n# 0day.today [2019-12-04] #", "_state": {"dependencies": 1659988328, "score": 1659957065}, "_internal": {"score_hash": "515adc0b6c9663d2abdf43c76119c58e"}}

Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace.CVE-2019-10639\n\nAn issue was discovered in the Linux kernel before 4.20.15.

Another contributing factor is incorrect marking of\n a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper\n with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.\n (CVE-2019-13272)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's

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):A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.(CVE-2018-16871)An issue was discovered in the Linux kernel before 4.18.7. In create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace.(CVE-2018-20855)An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled.(CVE-2018-20856)The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass.\n Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace.(CVE-2019-10639)** DISPUTED ** An issue was discovered in ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: This has been disputed as not an issue.(CVE-2019-12378)**DISPUTED** An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5. phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not being an issue because ?All the code touched by the referenced commit runs only at boot, before any user processes are started. Therefore, there is no possibility for an unprivileged user to control it.?.(CVE-2019-12380)** DISPUTED ** An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL.(CVE-2019-12381)** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used.(CVE-2019-12456)An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in netfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in netfc/llcp_core.c.(CVE-2019-12818)An issue was discovered in the Linux kernel before 5.0. The function\n __mdiobus_register() in driverset/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service.(CVE-2019-12819)A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in netfcetlink.c in the Linux kernel before 5.1.13 can be triggered by a malicious user-mode program that omits certain NFC attributes, leading to denial of service.(CVE-2019-12984)In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE:\n SELinux deny_ptrace might be a usable workaround in some environments.(CVE-2019-13272)In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages.(CVE-2019-13631)In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c.(CVE-2019-13648)In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default.(CVE-2019-14283)In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default.(CVE-2019-14284)In the Linux kernel before 4.16.4, a double-locking error in drivers/usb/dwc3/gadget.c may potentially cause a deadlock with f_hid.(CVE-2019-14763)An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/v4l2-core/v4l2-dev.c driver because drivers/media/radio/radio-raremono.c does not properly allocate memory.(CVE-2019-15211)An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit, related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)A flaw was found in the way the sit_init_net function in the Linux kernel handled resource cleanup on errors. This flaw allows an attacker to use the error conditions to crash the system.(CVE-2019-16994)Note:\n kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions in EulerOS Virtualization for ARM 64 3.0.2.0 return incorrect time information when executing the uname -a command.\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

bugfixes.\n\nThe following security bugs were fixed :\n\nCVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.\n\nThe Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).\n\nCVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.\n\nThe Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).\n\nThe set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).\n\nCVE-2019-10220: Added sanity checks on the pathnames passed to the user space. (bsc#1144903).\n\nCVE-2019-17666: rtlwifi: Fix potential overflow in P2P code (bsc#1154372).\n\nCVE-2019-17133: cfg80211 wireless extension did not reject a long SSID IE, leading to a Buffer Overflow (bsc#1153158).\n\nCVE-2019-16232: Fix a potential NULL pointer dereference in the Marwell libertas driver (bsc#1150465).\n\nCVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150452).\n\nCVE-2019-17055: The AF_ISDN network module in the Linux kernel did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bnc#1152782).\n\nCVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).\n\nCVE-2019-16413: The 9p filesystem did not protect i_size_write() properly, which caused an i_size_read() infinite loop and denial of service on SMP systems (bnc#1151347).\n\nCVE-2019-15902: A backporting issue was discovered that re-introduced the Spectre vulnerability it had aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).\n\nCVE-2019-15291: Fixed a NULL pointer dereference issue that could be caused by a malicious USB device (bnc#1146519).\n\nCVE-2019-15807: Fixed a memory leak in the SCSI module that could be abused to cause denial of service (bnc#1148938).\n\nCVE-2019-13272: Fixed a mishandled the recording of the credentials of a process that wants to create a ptrace relationship, which allowed local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker).\n(bnc#1140671).\n\nCVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's KVM hypervisor. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).\n\nCVE-2019-15505: An out-of-bounds issue had been fixed that could be caused by crafted USB device traffic (bnc#1147122).\n\nCVE-2017-18595: A double free in allocate_trace_buffer was fixed (bnc#1149555).\n\nCVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost functionality that translates virtqueue buffers to IOVs. A privileged guest user able to pass descriptors with invalid length to the host could use this flaw to increase their privileges on the host (bnc#1150112).\n\nCVE-2019-15216: A NULL pointer dereference was fixed that could be malicious USB device (bnc#1146361).\n\nCVE-2019-15924: A a NULL pointer dereference has been fixed in the drivers/net/ethernet/intel/fm10k module (bnc#1149612).\n\nCVE-2019-9456: An out-of-bounds write in the USB monitor driver has been fixed. This issue could lead to local escalation of privilege with System execution privileges needed. (bnc#1150025).\n\nCVE-2019-15926: An out-of-bounds access was fixed in the drivers/net/wireless/ath/ath6kl module. (bnc#1149527).\n\nCVE-2019-15927: An out-of-bounds access was fixed in the sound/usb/mixer module (bnc#1149522).\n\nCVE-2019-15666: There was an out-of-bounds array access in the net/xfrm module that could cause denial of service (bnc#1148394).\n\nCVE-2017-18379: An out-of-boundary access was fixed in the drivers/nvme/target module (bnc#1143187).\n\nCVE-2019-15219: A NULL pointer dereference was fixed that could be abused by a malicious USB device (bnc#1146519 1146524).\n\nCVE-2019-15220: A use-after-free issue was fixed that could be caused by a malicious USB device (bnc#1146519 1146526).\n\nCVE-2019-15221: A NULL pointer dereference was fixed that could be caused by a malicious USB device (bnc#1146519 1146529).\n\nCVE-2019-14814: A heap-based buffer overflow was fixed in the marvell wifi chip driver. That issue allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).\n\nCVE-2019-14815: A missing length check while parsing WMM IEs was fixed (bsc#1146512, bsc#1146514, bsc#1146516).\n\nCVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip driver was fixed. Local users would have abused this issue to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146516).\n\nCVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific socket option, an attacker could control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)\n\nCVE-2019-9506: The Bluetooth BR/EDR specification used to permit sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation. This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and inject arbitrary ciphertext without the victim noticing (bnc#1137865).\n\nCVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath was fixed (bnc#1146378).\n\nCVE-2019-15290: A NULL pointer dereference in ath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).\n\nCVE-2019-15239: A incorrect patch to net/ipv4 was fixed. By adding to a write queue between disconnection and re-connection, a local attacker could trigger multiple use-after-free conditions. This could result in kernel crashes or potentially in privilege escalation.\n(bnc#1146589)\n\nCVE-2019-15212: A double-free issue was fixed in drivers/usb driver (bnc#1146391).\n\nCVE-2016-10906: A use-after-free issue was fixed in drivers/net/ethernet/arc (bnc#1146584).\n\nCVE-2019-15211: A use-after-free issue caused by a malicious USB device was fixed in the drivers/media/v4l2-core driver (bnc#1146519).\n\nCVE-2019-15217: A a NULL pointer dereference issue caused by a malicious USB device was fixed in the drivers/media/usb/zr364xx driver (bnc#1146519).\n\nCVE-2019-15214: An a use-after-free issue in the sound subsystem was fixed (bnc#1146519).\n\nCVE-2019-15218: A NULL pointer dereference caused by a malicious USB device was fixed in the drivers/media/usb/siano driver (bnc#1146413).\n\nCVE-2019-15215: A use-after-free issue caused by a malicious USB device was fixed in the drivers/media/usb/cpia2 driver (bnc#1146425).\n\nCVE-2018-20976: A use-after-free issue was fixed in the fs/xfs driver (bnc#1146285).\n\nCVE-2017-18551: An out-of-bounds write was fixed in the drivers/i2c driver (bnc#1146163).\n\nCVE-2019-0154: An unprotected read access to i915 registers has been fixed that could have been abused to facilitate a local denial-of-service attack. (bsc#1135966)\n\nCVE-2019-0155: A privilege escalation vulnerability has been fixed in the i915 module that allowed batch buffers from user mode to gain super user privileges.

That issue allowed local users to cause a denial of\nservice (system crash) or possibly execute arbitrary code\n(bnc#1146512).\n\nCVE-2019-14815: A missing length check while parsing WMM IEs was fixed\n(bsc#1146512, bsc#1146514, bsc#1146516).\n\nCVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip\ndriver was fixed. Local users would have abused this issue to cause a\ndenial of service (system crash) or possibly execute arbitrary code\n(bnc#1146516).\n\nCVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific\nsocket option, an attacker could control a pointer in kernel land and\ncause an inet_csk_listen_stop general protection fault, or potentially\nexecute arbitrary code under certain circumstances. The issue can be\ntriggered as root (e.g., inside a default LXC container or with the\nCAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)\n\nCVE-2019-9506: The Bluetooth BR/EDR specification used to permit\nsufficiently low encryption key length and did not prevent an attacker\nfrom influencing the key length negotiation. This allowed practical\nbrute-force attacks (aka 'KNOB') that could decrypt traffic and inject\narbitrary ciphertext without the victim noticing (bnc#1137865).\n\nCVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath\nwas fixed (bnc#1146378).\n\nCVE-2019-15290: A NULL pointer dereference in\nath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).\n\nCVE-2019-15239: A incorrect patch to net/ipv4 was fixed.

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):Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.(CVE-2012-3400)The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive.(CVE-2013-2164)The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.(CVE-2013-2206)The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.(CVE-2013-6282)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)The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.(CVE-2019-11487)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.\n 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)A n issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.(CVE-2019-11810)An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.(CVE-2018-16880)An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8. There is a race condition leading to a use-after-free, related to net namespace cleanup.(CVE-2019-11815)A flaw was found in the Linux kernel in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ('root') can cause a system lock up and a denial of service. Versions from v4.18 and newer are vulnerable.(CVE-2019-3819)A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.(CVE-2019-3900)In the Linux Kernel before versions 4.20.8 and 4.19.21 a use-after-free error in the 'sctp_sendmsg()' function (net/sctp/socket.c) when handling SCTP_SENDALL flag can be exploited to corrupt memory.(CVE-2019-8956)A flaw was found in the Linux kernel's implementation of ext4 extent management. The kernel doesn't correctly initialize memory regions in the extent tree block which may be exported to a local user to obtain sensitive information by reading empty/uninitialized data from the filesystem.(CVE-2019-11833)An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).\n NOTE: The vendor disputes this issues as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference.(CVE-2019-12382)An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5. phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not being an issue because ?All the code touched by the referenced commit runs only at boot, before any user processes are started. Therefore, there is no possibility for an unprivileged user to control it.(CVE-2019-12380)An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function hclge_tm_schd_mode_vnet_base_cfg in the file drivers et/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.(CVE-2019- 15925)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-i1/4zname, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).(CVE-2019-12614)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/syset/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.(CVE-2019-18805)A flaw was found in the way PTRACE_TRACEME functionality was handled in the Linux kernel. The kernel's implementation of ptrace can inadvertently grant elevated permissions to an attacker who can then abuse the relationship between the tracer and the process being traced. This flaw could allow a local, unprivileged user to increase their privileges on the system or cause a denial of service.(CVE-2019-13272)An issue was discovered in ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux kernel through 5.1.5.

There is an unchecked\n kstrdup_const of node_info-i1/4zvdev_port.name, which\n might allow an attacker to cause a denial of service\n (NULL pointer dereference and system\n crash).(CVE-2019-12615)In parse_hid_report_descriptor\n in drivers/input/tablet/gtco.c in the Linux kernel\n through 5.2.1, a malicious USB device can send an HID\n report that triggers an out-of-bounds write during\n generation of debugging messages.(CVE-2019-13631)A\n vulnerability was found in the Linux kernelaEURtms floppy\n disk driver implementation. A local attacker with\n access to the floppy device could call set_geometry in\n drivers/block/floppy.c, which does not validate the\n sect and head fields, causing an integer overflow and\n out-of-bounds read. This flaw may crash the system or\n allow an attacker to gather information causing\n subsequent successful\n attacks.(CVE-2019-14283)check_input_term in\n sound/usb/mixer.c in the Linux kernel through 5.2.9\n mishandles recursion, leading to kernel stack\n exhaustion.(CVE-2019-15118)An issue was discovered in\n the Linux kernel before 5.2.6. There is a\n use-after-free caused by a malicious USB device in the\n drivers/media/v4l2-core/v4l2-dev.c driver because\n drivers/media/radio/radio-raremono.c does not properly\n allocate memory.(CVE-2019-15211)An issue was discovered\n in the Linux kernel before 5.0.10. There is a\n use-after-free in the sound subsystem because card\n disconnection causes certain data structures to be\n deleted too early. This is related to sound/core/init.c\n and sound/core/info.c.(CVE-2019-15214)An issue was\n discovered in the Linux kernel before 5.1.8. There is a\n NULL pointer dereference caused by a malicious USB\n device in the drivers/media/usb/siano/smsusb.c\n driver.(CVE-2019-15218)An issue was discovered in the\n Linux kernel before 5.1.8. There is a NULL pointer\n dereference caused by a malicious USB device in the\n drivers/usb/misc/sisusbvga/sisusb.c\n driver.(CVE-2019-15219)An issue was discovered in the\n Linux kernel before 5.2.1. There is a use-after-free\n caused by a malicious USB device in the\n driverset/wireless/intersil/p54/p54usb.c\n driver.(CVE-2019-15220)An issue was discovered in the\n Linux kernel before 5.1.17. There is a NULL pointer\n dereference caused by a malicious USB device in the\n sound/usb/line6/pcm.c driver.(CVE-2019-15221)An issue\n was discovered in the Linux kernel before 5.0.9. There\n is a use-after-free in atalk_proc_exit, related to\n net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and\n net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)An\n issue was discovered in xfs_setattr_nonsize in\n fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.\n XFS partially wedges when a chgrp fails on account of\n being out of disk quota. xfs_setattr_nonsize is failing\n to unlock the ILOCK after the xfs_qm_vop_chown_reserve\n call fails. This is primarily a local DoS attack\n vector, but it might result as well in remote DoS if\n the XFS filesystem is exported for instance via\n NFS.(CVE-2019-15538)An issue was discovered in the\n Linux kernel before 5.0.19. There is an out-of-bounds\n array access in __xfrm_policy_unlink, which will cause\n denial of service, because verify_newpolicy_info in\n net/xfrm/xfrm_user.c mishandles directory\n validation.(CVE-2019-15666)In the Linux kernel before\n 5.1.13, there is a memory leak in\n drivers/scsi/libsas/sas_expander.c when SAS expander\n discovery fails. This will cause a BUG and denial of\n service.(CVE-2019-15807)An issue was discovered in the\n Linux kernel before 5.0.5. There is a use-after-free\n issue when hci_uart_register_dev() fails in\n hci_uart_set_proto() in\n drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)An issue\n was discovered in the Linux kernel before 5.0.10.\n SMB2_write in fs/cifs/smb2pdu.c has a\n use-after-free.(CVE-2019-15919)An issue was discovered\n in the Linux kernel before 5.0.10. SMB2_read in\n fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was\n not fixed correctly in 5.0.10 see the 5.0.11 ChangeLog,\n which documents a memory leak.(CVE-2019-15920)An issue\n was discovered in the Linux kernel before 5.0.4. The 9p\n filesystem did not protect i_size_write() properly,\n which causes an i_size_read() infinite loop and denial\n of service on SMP systems.(CVE-2019-16413)An issue was\n discovered in can_can_gw_rcv in net/can/gw.c in the\n Linux kernel through 4.19.13. The CAN frame\n modification rules allow bitwise logical operations\n that can be also applied to the can_dlc field. Because\n of a missing check, the CAN drivers may write arbitrary\n content beyond the data registers in the CAN\n controller's I/O memory when processing can-gw\n manipulated outgoing frames. This is related to\n cgw_csum_xor_rel. An unprivileged user can trigger a\n system crash (general protection\n fault).(CVE-2019-3701)A flaw was found in the Linux\n kernel's Marvell wifi chip driver. A heap overflow in\n mwifiex_update_bss_desc_with_ie function in\n marvell/mwifiex/scan.c allows remote attackers to cause\n a denial of service(system crash) or execute arbitrary\n code.(CVE-2019-3846)A new software page cache side\n channel attack scenario was discovered in operating\n systems that implement the very common 'page cache'\n caching mechanism. A malicious user/process could use\n 'in memory' page-cache knowledge to infer access\n timings to shared memory and gain knowledge which can\n be used to reduce effectiveness of cryptographic\n strength by monitoring algorithmic behavior, infer\n access patterns of memory to determine code paths\n taken, and exfiltrate data to a blinded attacker\n through page-granularity access times as a\n side-channel.(CVE-2019-5489)In the Android kernel in\n the video driver there is a kernel pointer leak due to\n a WARN_ON statement. This could lead to local\n information disclosure with System execution privileges\n needed. User interaction is not needed for\n exploitation.(CVE-2019-9455)A vulnerability was found\n in the arch/x86/lib/insn-eval.c function in the Linux\n kernel. An attacker could corrupt the memory due to a\n flaw in use-after-free access to an LDT entry caused by\n a race condition between modify_ldt() and a #BR\n exception for an MPX bounds violation.(CVE-2019-13233)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.
