    * A flaw was found in the way the Linux kernel's 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,     Important)

    * A stack overflow flaw caused by infinite recursion was found in the way     the Linux kernel's UDF file system implementation processed indirect ICBs.
    An attacker with physical access to the system could use a specially     crafted UDF image to crash the system. (CVE-2014-6410, Low)

    Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-9322.
    The CVE-2014-3673 issue was discovered by Liu Wei of Red Hat.

    Bug fixes:

    * This update fixes a race condition issue between the sock_queue_err_skb     function and sk_forward_alloc handling in the socket error queue     (MSG_ERRQUEUE), which could occasionally cause the kernel, for example when     using PTP, to incorrectly track allocated memory for the error queue, in     which case a traceback would occur in the system log. (BZ#1155427)

    * The zcrypt device driver did not detect certain crypto cards and the     related domains for crypto adapters on System z and s390x architectures.
    Consequently, it was not possible to run the system on new crypto hardware.
    This update enables toleration mode for such devices so that the system     can make use of newer crypto hardware. (BZ#1158311)

    * After mounting and unmounting an XFS file system several times     consecutively, the umount command occasionally became unresponsive.
    This was caused by the xlog_cil_force_lsn() function that was not waiting     for completion as expected. With this update, xlog_cil_force_lsn() has been     modified to correctly wait for completion, thus fixing this bug.
    (BZ#1158325)

    * When using the ixgbe adapter with disabled LRO and the tx-usec or rs-usec     variables set to 0, transmit interrupts could not be set lower than the     default of 8 buffered tx frames. Consequently, a delay of TCP transfer     occurred. The restriction of a minimum of 8 buffered frames has been     removed, and the TCP delay no longer occurs. (BZ#1158326)

    * The offb driver has been updated for the QEMU standard VGA adapter,     fixing an incorrect displaying of colors issue. (BZ#1158328)

    * Under certain circumstances, when a discovered MTU expired, the IPv6     connection became unavailable for a short period of time. This bug has been     fixed, and the connection now works as expected. (BZ#1161418)

    * A low throughput occurred when using the dm-thin driver to write to     unprovisioned or shared chunks for a thin pool with the chunk size bigger     than the max_sectors_kb variable. (BZ#1161420)

    * Large write workloads on thin LVs could cause the iozone and smallfile     utilities to terminate unexpectedly. (BZ#1161421)

This security upload has been prepared in cooperation of the Debian Kernel, Security and LTS Teams and features the upstream stable release 2.6.32.64 (see https://lkml.org/lkml/2014/11/23/181 for more information for that). It fixes the CVEs described below.

Note: if you are using the openvz flavors, please consider three things: a.) we haven't got any feedback on them (while we have for all other flavors) b.) so do your test before deploying them and c.) once you have done so, please give feedback to debian-lts@lists.debian.org. 

If you are not using openvz flavors, please still consider b+c :-)

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).

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