The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3586 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4     and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment     reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a     denial of service on the system. (CVE-2018-5391)

    * kernel: out-of-bounds access in the show_timer function in kernel/time/posix-timers.c (CVE-2017-18344)

    * kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact     (CVE-2018-10675)

    * kernel: Integer overflow in Linux's create_elf_tables function (CVE-2018-14634)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank Juha-Matti Tilli (Aalto University - Department of Communications and     Networking and Nokia Bell Labs) for reporting CVE-2018-5391 and Qualys Research Labs for reporting     CVE-2018-14634.

    Bug Fix(es):

    * The kernel-rt packages have been upgraded to the 3.10.0-693.43.1 source tree, which provides a number of     bug fixes over the previous version. (BZ#1632422)

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-3620: Local attackers on baremetal systems     could use speculative code patterns on hyperthreaded     processors to read data present in the L1 Datacache used     by other hyperthreads on the same CPU core, potentially     leaking sensitive data. (bnc#1087081).

  - CVE-2018-3646: Local attackers in virtualized guest     systems could use speculative code patterns on     hyperthreaded processors to read data present in the L1     Datacache used by other hyperthreads on the same CPU     core, potentially leaking sensitive data, even from     other virtual machines or the host system.
    (bnc#1089343).

  - CVE-2018-5390 aka 'SegmentSmack': The Linux Kernel can     be forced to make very expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for     every incoming packet which can lead to a denial of     service (bnc#1102340).

  - CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP     packet reassembly could be used by remote attackers to     consume lots of CPU time (bnc#1103097).

  - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allowed     attackers to cause a denial of service (use-after-free)     (bnc#1103119).

  - CVE-2017-18344: The timer_create syscall implementation     in kernel/time/posix-timers.c didn't properly validate     the sigevent->sigev_notify field, which leads to     out-of-bounds access in the show_timer function (called     when /proc/$PID/timers is read). This allowed userspace     applications to read arbitrary kernel memory (on a     kernel built with CONFIG_POSIX_TIMERS and     CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).

  - CVE-2018-9385: When printing the 'driver_override'     option from with-in the amba driver, a very long line     could expose one additional uninitialized byte     (bnc#1100491).

  - CVE-2018-13053: The alarm_timer_nsleep function in     kernel/time/alarmtimer.c had an integer overflow via a     large relative timeout because ktime_add_safe is not     used (bnc#1099924).

  - CVE-2018-13405: The inode_init_owner function in     fs/inode.c allowed local users to create files with an     unintended group ownership, in a scenario where a     directory is SGID to a certain group and is writable by     a user who is not a member of that group. Here, the     non-member can trigger creation of a plain file whose     group ownership is that group. The intended behavior was     that the non-member can trigger creation of a directory     (but not a plain file) whose group ownership is that     group. The non-member can escalate privileges by making     the plain file executable and SGID (bnc#1100416).

  - CVE-2018-13406: An integer overflow in the     uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c could result in local     attackers being able to crash the kernel or potentially     elevate privileges because kmalloc_array is not used     (bnc#1098016 1100418).

  - CVE-2018-5814: Multiple race condition errors when     handling probe, disconnect, and rebind operations could     be exploited to trigger a use-after-free condition or a     NULL pointer dereference by sending multiple USB over IP     packets (bnc#1096480).

The update package also includes non-security fixes. See advisory for details.

The openSUSE Leap 42.3 kernel was updated to 4.4.143 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-18344: The timer_create syscall implementation     in kernel/time/posix-timers.c didn't properly validate     the sigevent->sigev_notify field, which leads to     out-of-bounds access in the show_timer function (called     when /proc/$PID/timers is read). This allowed userspace     applications to read arbitrary kernel memory (on a     kernel built with CONFIG_POSIX_TIMERS and     CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).

  - CVE-2018-10880: Linux kernel is vulnerable to a     stack-out-of-bounds write in the ext4 filesystem code     when mounting and writing to a crafted ext4 image in     ext4_update_inline_data(). An attacker could use this to     cause a system crash and a denial of service.
    (bnc#1099845)

  - CVE-2018-10881: A flaw was found in the ext4 filesystem.
    A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and a     system crash by mounting and operating on a crafted ext4     filesystem image. (bnc#1099864)

  - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allowed     attackers to cause a denial of service (use-after-free)     (bnc#1103119).

  - CVE-2018-3620: Systems with microprocessors utilizing     speculative execution and address translations may allow     unauthorized disclosure of information residing in the     L1 data cache to an attacker with local user access via     a terminal page fault and a side-channel analysis     (bnc#1087081 1089343 ).

  - CVE-2018-3646: Systems with microprocessors utilizing     speculative execution and address translations may allow     unauthorized disclosure of information residing in the     L1 data cache to an attacker with local user access with     guest OS privilege via a terminal page fault and a     side-channel analysis (bnc#1089343 1104365).

  - CVE-2018-5390 aka 'SegmentSmack': The Linux kernel could     be forced to make very expensive calls to     tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for     every incoming packet which can lead to a denial of     service (bnc#1102340).

The version of Arista Networks CloudVision Portal running on the remote device is affected by a denial of service (DoS) vulnerability. The Linux kernel is vulnerable to a DoS attack with low rates of specially modified packets targeting IP fragment re-assembly. An remote, unauthenticated attacker can cause a DoS condition by sending specially crafted IP fragments. This vulnerability is caused by the increase of the IP fragment reassembly queue size in the Linux kernel.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. To retrieve patch level information this plugin requires the HTTP credentials of the web console.

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.
