installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-2574 advisory.\n\n - The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c. (CVE-2013-4312)\n\n - The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application. (CVE-2015-8543)\n\n - The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data. (CVE-2016-2117)\n\n - The filesystem layer in the Linux kernel before 4.5.5 proceeds with post-rename operations after an OverlayFS file is renamed to a self-hardlink, which allows local users to cause a denial of service (system crash) via a rename system call, related to fs/namei.c and fs/open.c. (CVE-2016-6198)\n\n - Race condition in arch/x86/mm/tlb.c in the Linux kernel before 4.4.1 allows local users to gain privileges by triggering access to a paging structure by a different CPU. (CVE-2016-2069)\n\n - The IPv4 implementation in the Linux kernel before 4.5.2 mishandles destruction of device objects, which allows guest OS users to cause a denial of service (host OS networking outage) by arranging for a large number of IP addresses. (CVE-2016-3156)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls. (CVE-2016-4581)\n\n - fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes. (CVE-2016-2847)\n\n - fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local users to obtain sensitive pre-truncation information from a file via a clone action. (CVE-2015-8374)\n\n - Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. (CVE-2016-5829)\n\n - The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8844)\n\n - The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8845)\n\n - The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 4.2 allows local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket. (CVE-2015-8956)\n\n - The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. (CVE-2016-2053)\n\n - Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. (CVE-2016-2384)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite loop) by making a H_CEDE hypercall during the existence of a suspended transaction. (CVE-2016-5412)\n\n - drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation. (CVE-2016-6327)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a double fetch vulnerability. (CVE-2016-6480)\n\n - fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic. (CVE-2015-8746)\n\n - drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use- after-free) via crafted packets. (CVE-2015-8812)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd. (CVE-2016-3699)\n\n - The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841)\n\n - Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf system calls. (CVE-2016-4794)\n\n - The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call. (CVE-2016-5828)\n\n - Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by changing a certain string, aka a double fetch vulnerability.

(CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which\n allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA\n timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when\n CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite\n loop) by making a H_CEDE hypercall during the existence of a suspended transaction. (CVE-2016-5412)\n\n - drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a\n denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a\n device write operation. (CVE-2016-6327)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel\n through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by\n changing a certain size value, aka a double fetch vulnerability. (CVE-2016-6480)\n\n - fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory\n for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL\n pointer dereference and panic) via crafted network traffic. (CVE-2015-8746)\n\n - drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error\n conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use-\n after-free) via crafted packets. (CVE-2015-8812)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel\n before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service\n (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a\n certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted\n with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute\n untrusted code by appending ACPI tables to the initrd.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted. With this update, the underlying source code has been fixed, and extent tree corruption no longer occurs in the described situation.

Consequently, a kernel panic occurred. This\n update prevents the described problem. As a result, the\n kernel panic no longer occurs.\n\n - Previously, memory corruption by copying data into the\n wrong memory locations sometimes occurred, because the\n __copy_tofrom_user() function was returning incorrect\n values. This update fixes the __copy_tofrom_user()\n function so that it no longer returns larger values than\n the number of bytes it was asked to copy. As a result,\n memory corruption no longer occurs in he described\n scenario.\n\n - Previously, guest virtual machines (VMs) on a Hyper-V\n server cluster got in some cases rebooted during the\n graceful node failover test, because the host kept\n sending heartbeat packets independently of guests\n responding to them. This update fixes the bug by\n properly responding to all the heartbeat messages in the\n queue, even if they are pending. As a result, guest VMs\n no longer get rebooted under the described\n circumstances.\n\n - When the 'punching hole' feature of the fallocate\n utility was used on an ext4 file system inode with\n extent depth of 1, the extent tree of the inode\n sometimes became corrupted. With this update, the\n underlying source code has been fixed, and extent tree\n corruption no longer occurs in the described situation.\"\n );\n # https://listserv.fnal.gov/scripts/wa.exe?A2=ind1702&L=scientific-linux-errata&F=&S=&P=4925\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://www.nessus.org/u?e2a5df30\"\n );\n script_set_attribute(attribute:\"solution\", value:\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-abi-whitelists\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-i686\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-x86_64\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-doc\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-firmware\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-headers\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"x-cpe:/o:fermilab:scientific_linux\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2016/08/06\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2017/02/23\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2017/02/24\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_copyright(english:\"This script is Copyright (C) 2017-2021 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n script_family(english:\"Scientific Linux Local Security Checks\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/cpu\", \"Host/RedHat/release\", \"Host/RedHat/rpm-list\");\n\n exit(0);\n}\n\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"misc_func.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nrelease = get_kb_item(\"Host/RedHat/release\");\nif (isnull(release) || \"Scientific Linux \" >!< release) audit(AUDIT_HOST_NOT, \"running Scientific Linux\");\nos_ver = pregmatch(pattern: \"Scientific Linux.*release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Scientific Linux\");\nos_ver = os_ver[1];\nif (!

There is an information leak in file 'sound/core/timer.c' of the latest mainline Linux kernel, the stack object aEURoetreadaEUR has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak.(CVE-2016-4569)\n\n - A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object aEURoer1aEUR has a total size of 32 bytes. Its field aEURoeeventaEUR and aEURoevalaEUR both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is freed with free_percpu() which triggers async pcpu_balance_work and then pcpu_extend_area_map could use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254. However, the value returned as the total length is the sum of *claimed* sizes, not the actual amount collected. And that's what will be passed to readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality in overlayfs did not verify the upper dentry for staleness. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to panic or crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.(CVE-2016-6198)\n\n - System using the infiniband support module ib_srpt were vulnerable to a denial of service by system crash by a local attacker who is able to abort writes to a device using this initiator.(CVE-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.(CVE-2016-7097)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

These 8 bytes\n padding bytes are sent to user without being\n initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in\n net/x25/x25_facilities.c in the Linux kernel before\n 4.5.5 does not properly initialize a certain data\n structure, which allows attackers to obtain sensitive\n information from kernel stack memory via an X.25 Call\n Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not\n properly traverse a mount propagation tree in a certain\n case involving a slave mount, which allows local users\n to cause a denial of service (NULL pointer dereference\n and OOPS) via a crafted series of mount system\n calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using\n previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is\n freed with free_percpu() which triggers async\n pcpu_balance_work and then pcpu_extend_area_map could\n use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in\n drivers/net/ppp/ppp_generic.c in the Linux kernel\n before 4.5.2 allows local users to cause a denial of\n service (memory corruption and system crash, or\n spinlock) or possibly have unspecified other impact by\n removing a network namespace, related to the\n ppp_register_net_channel and ppp_unregister_channel\n functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads\n of NM entries are not supposed to contain NUL. When\n such entry is processed, only the part prior to the\n first NUL goes into the concatenation (i.e. the\n directory entry name being encoded by a bunch of NM\n entries). The process stops when the amount collected\n so far + the claimed amount in the current NM entry\n exceed 254. However, the value returned as the total\n length is the sum of *claimed* sizes, not the actual\n amount collected. And that's what will be passed to\n readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32\n bit processes on 64 bit systems. This flaw will allow\n attackers to alter arbitrary kernel memory when\n unloading a kernel module. This action is usually\n restricted to root-privileged users but can also be\n leveraged if the kernel is compiled with CONFIG_USER_NS\n and CONFIG_NET_NS and the user is granted elevated\n privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial\n of Service, heap disclosure, or further impact was\n found in setsockopt(). The function call is normally\n restricted to root, however some processes with\n cap_sys_admin may also be able to trigger this flaw in\n privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux\n kernel's memory subsystem handled the copy-on-write\n (COW) breakage of private read-only memory mappings. An\n unprivileged, local user could use this flaw to gain\n write access to otherwise read-only memory mappings and\n thus increase their privileges on the\n system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate\n limiting as implemented in the Linux kernel's\n networking subsystem allowed an off-path attacker to\n leak certain information about a given connection by\n creating congestion on the global challenge ACK rate\n limit counter and then measuring the changes by probing\n packets. An off-path attacker could use this flaw to\n either terminate TCP connection and/or inject payload\n into non-secured TCP connection between two endpoints\n on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in\n the Linux kernel's hiddev driver. This flaw could allow\n a local attacker to corrupt kernel memory, possible\n privilege escalation or crashing the\n system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed\n children processes, an attacker can convince the Linux\n kernel audit subsystem can create corrupt records which\n may allow an attacker to misrepresent or evade logging\n of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality\n in overlayfs did not verify the upper dentry for\n staleness. A local, unprivileged user could use the\n rename syscall on overlayfs on top of xfs to panic or\n crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not\n detect hard links on overlayfs. A local, unprivileged\n user could use the rename syscall on overlayfs on top\n of xfs to crash the system.(CVE-2016-6198)\n\n - System using the infiniband support module ib_srpt were\n vulnerable to a denial of service by system crash by a\n local attacker who is able to abort writes to a device\n using this initiator.(CVE-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial\n of service (out-of-bounds access or system crash) by\n changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in\n the Linux kernel before 4.0 mismanages locks during\n certain migrations, which allows local users to gain\n privileges via a crafted application, aka Android\n internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in\n the Linux kernel before 4.0 mismanages locks during\n certain migrations, which allows local users to gain\n privileges via a crafted application, aka Android\n internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in\n tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an\n incorrect selective acknowledgment to existing\n connections, possibly resetting a\n connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad\n VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local\n Area Network(CONFIG_VXLAN) with Transparent Ethernet\n Bridging(TEB) GRO support, is vulnerable to a stack\n overflow issue. It could occur while receiving large\n packets via GRO path, as an unlimited recursion could\n unfold in both VLAN and TEB modules, leading to a stack\n corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a\n panic in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as\n weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but\n doesn't clear the setgid bit in a similar way. This\n could allow a local user to gain group privileges via\n certain setgid applications.(CVE-2016-7097)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

CVE-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104).\n\n - CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement (bnc#986362).\n\n - CVE-2016-5829: Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call (bnc#986572).\n\n - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure was initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bnc#984755).\n\n - CVE-2016-5244: The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel did not initialize a certain structure member, which allowed remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message (bnc#983213).\n\n - CVE-2016-1583: The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling (bnc#983143).\n\n - CVE-2016-4913: The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel mishandled NM (aka alternate name) entries containing \\0 characters, which allowed local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem (bnc#980725).\n\n - CVE-2016-4580: The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel did not properly initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request (bnc#981267).\n\n - CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions (bnc#980371).\n\n - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bnc#979867).\n\n - CVE-2015-7833: The usbvision driver in the Linux kernel allowed physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor (bnc#950998).\n\n - CVE-2016-2187: The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#971944).\n\n - CVE-2016-4482: The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call (bnc#978401).\n\n - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bnc#979548).\n\n - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762).\n\n - CVE-2016-4485: The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel did not initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory by reading a message (bnc#978821).\n\n -

bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143).\n\n - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.\n (bsc#979548)\n\n - CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.

If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate)\n\nBug Fix(es) :\n\n* Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter.\nAs a result, the kernel no longer panics in the described scenario.\n(BZ#1377472)\n\n* When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.(BZ#1372266)\n\n* Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario.\n(BZ#1379596)\n\n* When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain.

With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances.\n(BZ#1375637)\n\n* When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. (BZ#1381592)\n\n* When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message: 'Medium access timeout failure.

The second problem was related\nto the mtime and ctime time stamp updates, which got lost when a GFS2\nfile was written to from one node and read from or written to from\nanother node. With this update, a set of patches has been applied that\nfix these problems. As a result, the time stamps of GFS2 files are now\nhandled correctly.

An unprivileged, local user could\n potentially use this flaw to escalate their privileges\n on the system. (CVE-2016-1583, Important)\n\n - It was reported that on s390x, the fork of a process\n with four page table levels will cause memory corruption\n with a variety of symptoms. All processes are created\n with three level page table and a limit of 4TB for the\n address space. If the parent process has four page table\n levels with a limit of 8PB, the function that duplicates\n the address space will try to copy memory areas outside\n of the address space limit for the child process.\n (CVE-2016-2143, Moderate)\n\nBug Fix(es) :\n\n - Use of a multi-threaded workload with high memory\n mappings sometiems caused a kernel panic, due to a race\n condition between the context switch and the pagetable\n upgrade. This update fixes the switch_mm() by using the\n complete asce parameter instead of the asce_bits\n parameter. As a result, the kernel no longer panics in\n the described scenario.\n\n - When iptables created the Transmission Control Protocol\n (TCP) reset packet, a kernel crash could occur due to\n uninitialized pointer to the TCP header within the\n Socket Buffer (SKB). This update fixes the transport\n header pointer in TCP reset for both IPv4 and IPv6, and\n the kernel no longer crashes in the described situation.\n\n - Previously, when the Enhanced Error Handling (EEH)\n mechanism did not block the PCI configuration space\n access and an error was detected, a kernel panic\n occurred. This update fixes EEH to fix this problem. As\n a result, the kernel no longer panics in the described\n scenario.\n\n - When the lockd service failed to start up completely,\n the notifier blocks were in some cases registered on a\n notification chain multiple times, which caused the\n occurrence of a circular list on the notification chain.\n Consequently, a soft lock-up or a kernel oops occurred.\n With this update, the notifier blocks are unregistered\n if lockd fails to start up completely, and the soft\n lock-ups or the kernel oopses no longer occur under the\n described circumstances.\n\n - When the Fibre Channel over Ethernet (FCoE) was\n configured, the FCoE MaxFrameSize parameter was\n incorrectly restricted to 1452. With this update, the\n NETIF_F_ALL_FCOE symbol is no longer ignored, which\n fixes this bug. MaxFrameSize is now restricted to 2112,\n which is the correct value.\n\n - When the fnic driver was installed on Cisco UCS Blade\n Server, the discs were under certain circumstances put\n into the offline state with the following error message:\n 'Medium access timeout failure. Offlining disk!'. This\n update fixes fnic to set the Small Computer System\n Interface (SCSI) status as DID_ABORT after a successful\n abort operation. As a result, the discs are no longer\n put into the offlined state in the described situation.\"\n );\n # https://listserv.fnal.gov/scripts/wa.exe?A2=ind1611&L=scientific-linux-errata&F=&S=&P=3698\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://www.nessus.org/u?de3aa8c5\"\n );\n script_set_attribute(attribute:\"solution\", value:\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:POC/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:P/RL:O/RC:C\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-abi-whitelists\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-i686\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debuginfo-common-x86_64\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-doc\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-firmware\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-headers\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:python-perf-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"x-cpe:/o:fermilab:scientific_linux\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2016/04/27\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2016/11/15\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2016/11/22\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_copyright(english:\"This script is Copyright (C) 2016-2021 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n script_family(english:\"Scientific Linux Local Security Checks\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/cpu\", \"Host/RedHat/release\", \"Host/RedHat/rpm-list\");\n\n exit(0);\n}\n\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"misc_func.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nrelease = get_kb_item(\"Host/RedHat/release\");\nif (isnull(release) || \"Scientific Linux \" >!< release) audit(AUDIT_HOST_NOT, \"running Scientific Linux\");\nos_ver = pregmatch(pattern: \"Scientific Linux.*release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Scientific Linux\");\nos_ver = os_ver[1];\nif (!

{"lastseen": "2023-05-18T14:28:53", "description": "From Red Hat Security Advisory 2016:2124 :\n\nAn update for kernel is now available for Red Hat Enterprise Linux 5.\n\nRed Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. (CVE-2016-5195, Important)\n\n* It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system.\n(CVE-2016-1583, Important)\n\nRed Hat would like to thank Phil Oester for reporting CVE-2016-5195.\n\nBug Fix(es) :\n\n* In some cases, a kernel crash or file system corruption occurred when running journal mode 'ordered'. The kernel crash was caused by a NULL pointer dereference due to a race condition between two journal functions. The file system corruption occurred due to a race condition between the do_get_write_access() function and buffer writeout. This update fixes both race conditions. As a result, neither the kernel crash, nor the file system corruption now occur. (BZ#1067708)\n\n* Prior to this update, some Global File System 2 (GFS2) files had incorrect time stamp values due to two problems with handling time stamps of such files.
