The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2446-1 advisory.

    Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack     Segment (SS) register in the x86 architecture. A local attacker could exploit this flaw to gain     administrative privileges. (CVE-2014-9322)

    An information leak in the Linux kernel was discovered that could leak the high 16 bits of the kernel     stack address on 32-bit Kernel Virtual Machine (KVM) paravirt guests. A user in the guest OS could exploit     this leak to obtain information that could potentially be used to aid in attacking the kernel.
    (CVE-2014-8134)

    Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace subsystem of the Linux kernel does     not properly handle private syscall numbers. A local user could exploit this flaw to cause a denial of     service (OOPS). (CVE-2014-7826)

    A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control Transmission Protocol)     implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a     denial of service (system crash). (CVE-2014-3673)

    A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control Transmission Protocol)     implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a     denial of service (panic). (CVE-2014-3687)

    It was discovered that excessive queuing by SCTP (Stream Control Transmission Protocol) implementation in     the Linux kernel can cause memory pressure. A remote attacker could exploit this flaw to cause a denial of     service. (CVE-2014-3688)

    Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in how the perf subsystem of the Linux     kernel handles private systecall numbers. A local user could exploit this to cause a denial of service     (OOPS) or bypass ASLR protections via a crafted application. (CVE-2014-7825)

    The KVM (kernel virtual machine) subsystem of the Linux kernel miscalculates the number of memory pages     during the handling of a mapping failure. A guest OS user could exploit this to cause a denial of service     (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges.
    (CVE-2014-8369)

    Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack     Segment (SS) register on the x86 architecture. A local attacker could exploit this flaw to cause a denial     of service (panic). (CVE-2014-9090)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 11 Service Pack 1 LTSS kernel was updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

  - CVE-2013-4299: Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allowed remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block device (bnc#846404).

  - CVE-2014-8160: SCTP firewalling failed until the SCTP     module was loaded (bnc#913059).

  - CVE-2014-9584: The parse_rock_ridge_inode_internal     function in fs/isofs/rock.c in the Linux kernel before     3.18.2 did not validate a length value in the Extensions     Reference (ER) System Use Field, which allowed local     users to obtain sensitive information from kernel memory     via a crafted iso9660 image (bnc#912654).

  - CVE-2014-9585: The vdso_addr function in     arch/x86/vdso/vma.c in the Linux kernel through 3.18.2     did not properly choose memory locations for the vDSO     area, which made it easier for local users to bypass the     ASLR protection mechanism by guessing a location at the     end of a PMD (bnc#912705).

  - CVE-2014-9420: The rock_continue function in     fs/isofs/rock.c in the Linux kernel through 3.18.1 did     not restrict the number of Rock Ridge continuation     entries, which allowed local users to cause a denial of     service (infinite loop, and system crash or hang) via a     crafted iso9660 image (bnc#911325).

  - CVE-2014-0181: The Netlink implementation in the Linux     kernel through 3.14.1 did not provide a mechanism for     authorizing socket operations based on the opener of a     socket, which allowed local users to bypass intended     access restrictions and modify network configurations by     using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program (bnc#875051).

  - CVE-2010-5313: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 2.6.38 allowed L2 guest OS users     to cause a denial of service (L1 guest OS crash) via a     crafted instruction that triggers an L2 emulation     failure report, a similar issue to CVE-2014-7842     (bnc#907822).

  - CVE-2014-7842: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 3.17.4 allowed guest OS users to     cause a denial of service (guest OS crash) via a crafted     application that performs an MMIO transaction or a PIO     transaction to trigger a guest userspace emulation error     report, a similar issue to CVE-2010-5313 (bnc#905312).

  - CVE-2014-3688: The SCTP implementation in the Linux     kernel before 3.17.4 allowed remote attackers to cause a     denial of service (memory consumption) by triggering a     large number of chunks in an associations output queue,     as demonstrated by ASCONF probes, related to     net/sctp/inqueue.c and net/sctp/sm_statefuns.c     (bnc#902351).

  - CVE-2014-3687: The sctp_assoc_lookup_asconf_ack function     in net/sctp/associola.c in the SCTP implementation in     the Linux kernel through 3.17.2 allowed remote attackers     to cause a denial of service (panic) via duplicate     ASCONF chunks that trigger an incorrect uncork within     the side-effect interpreter (bnc#902349).

  - CVE-2014-3673: The SCTP implementation in the Linux     kernel through 3.17.2 allowed remote attackers to cause     a denial of service (system crash) via a malformed     ASCONF chunk, related to net/sctp/sm_make_chunk.c and     net/sctp/sm_statefuns.c (bnc#902346).

  - CVE-2014-7841: The sctp_process_param function in     net/sctp/sm_make_chunk.c in the SCTP implementation in     the Linux kernel before 3.17.4, when ASCONF is used,     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) via a     malformed INIT chunk (bnc#905100).

  - CVE-2014-8709: The ieee80211_fragment function in     net/mac80211/tx.c in the Linux kernel before 3.13.5 did     not properly maintain a certain tail pointer, which     allowed remote attackers to obtain sensitive cleartext     information by reading packets (bnc#904700).

  - CVE-2013-7263: The Linux kernel before 3.12.4 updated     certain length values before ensuring that associated     data structures have been initialized, which allowed     local users to obtain sensitive information from kernel     stack memory via a (1) recvfrom, (2) recvmmsg, or (3)     recvmsg system call, related to net/ipv4/ping.c,     net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and     net/ipv6/udp.c (bnc#857643).

  - CVE-2012-6657: The sock_setsockopt function in     net/core/sock.c in the Linux kernel before 3.5.7 did not     ensure that a keepalive action is associated with a     stream socket, which allowed local users to cause a     denial of service (system crash) by leveraging the     ability to create a raw socket (bnc#896779).

  - CVE-2014-3185: Multiple buffer overflows in the     command_port_read_callback function in     drivers/usb/serial/whiteheat.c in the Whiteheat USB     Serial Driver in the Linux kernel before 3.16.2 allowed     physically proximate attackers to execute arbitrary code     or cause a denial of service (memory corruption and     system crash) via a crafted device that provides a large     amount of (1) EHCI or (2) XHCI data associated with a     bulk response (bnc#896391).

  - CVE-2014-3184: The report_fixup functions in the HID     subsystem in the Linux kernel before 3.16.2 might allow     physically proximate attackers to cause a denial of     service (out-of-bounds write) via a crafted device that     provides a small report descriptor, related to (1)     drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3)     drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c,     (5) drivers/hid/hid-petalynx.c, and (6)     drivers/hid/hid-sunplus.c (bnc#896390).

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions. On hosts with an Intel processor and     invept VM exit support, an unprivileged guest user     could use these instructions to crash the     guest.(CVE-2014-3645)

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invvpid     (Invalidate Translations Based on VPID) instructions.
    On hosts with an Intel processor and invppid VM exit     support, an unprivileged guest user could use these     instructions to crash the guest.(CVE-2014-3646)

  - A flaw was found in the way the Linux kernel's KVM     subsystem handled non-canonical addresses when     emulating instructions that change the RIP (for     example, branches or calls). A guest user with access     to an I/O or MMIO region could use this flaw to crash     the guest.(CVE-2014-3647)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled malformed Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3673)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled duplicate Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3687)

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled the association's output queue. A remote     attacker could send specially crafted packets that     would cause the system to use an excessive amount of     memory, leading to a denial of service.(CVE-2014-3688)

  - It was found that the Linux kernel's KVM implementation     did not ensure that the host CR4 control register value     remained unchanged across VM entries on the same     virtual CPU. A local, unprivileged user could use this     flaw to cause a denial of service on the     system.(CVE-2014-3690)

  - An out-of-bounds memory access flaw was found in the     Linux kernel's system call auditing implementation. On     a system with existing audit rules defined, a local,     unprivileged user could use this flaw to leak kernel     memory to user space or, potentially, crash the     system.(CVE-2014-3917)

  - A flaw was found in the way Linux kernel's Transparent     Huge Pages (THP) implementation handled non-huge page     migration. A local, unprivileged user could use this     flaw to crash the kernel by migrating transparent     hugepages.(CVE-2014-3940)

  - The capabilities implementation in the Linux kernel     before 3.14.8 does not properly consider that     namespaces are inapplicable to inodes, which allows     local users to bypass intended chmod restrictions by     first creating a user namespace, as demonstrated by     setting the setgid bit on a file with group ownership     of root.(CVE-2014-4014)

  - An information leak flaw was found in the RAM Disks     Memory Copy (rd_mcp) backend driver of the iSCSI Target     subsystem of the Linux kernel. A privileged user could     use this flaw to leak the contents of kernel memory to     an iSCSI initiator remote client.(CVE-2014-4027)
