"This Linux kernel update fixes various security issues and bugs in the
SUSE Linux Enterprise 10 SP4 kernel.

The following security issues have been fixed :

  - A race condition in ptrace(2) could be used by local
    attackers to crash the kernel and/or execute code in
    kernel context. (CVE-2013-0871)

  - Avoid side channel information leaks from the ptys via
    ptmx, which allowed local attackers to guess keypresses.
    (CVE-2013-0160)

  - Avoid leaving bprm->interp on the stack which might have
    leaked information from the kernel to userland
    attackers. (CVE-2012-4530)

  - The msr_open function in arch/x86/kernel/msr.c in the
    Linux kernel allowed local users to bypass intended
    capability restrictions by executing a crafted
    application as root, as demonstrated by msr32.c.
    (CVE-2013-0268)

  - The Xen netback functionality in the Linux kernel
    allowed guest OS users to cause a denial of service
    (loop) by triggering ring pointer corruption.
    (CVE-2013-0216)

  - The pciback_enable_msi function in the PCI backend
    driver (drivers/xen/pciback/conf_space_capability_msi.c)
    in Xen for the Linux kernel allowed guest OS users with
    PCI device access to cause a denial of service via a
    large number of kernel log messages. NOTE: some of these
    details are obtained from third-party information.
    (CVE-2013-0231)

Also the following non-security bugs have been fixed :

S/390 :

  - s390x: tty struct used after free (bnc#809692,
    LTC#90216).

  - s390x/kernel: sched_clock() overflow (bnc#799611,
    LTC#87978).

  - qeth: set new mac even if old mac is gone
    (bnc#789012,LTC#86643).

  - qeth: set new mac even if old mac is gone (2)
    (bnc#792697,LTC#87138).

  - qeth: fix deadlock between recovery and bonding driver
    (bnc#785101,LTC#85905).

  - dasd: check count address during online setting
    (bnc#781485,LTC#85346).

  - hugetlbfs: add missing TLB invalidation
    (bnc#781485,LTC#85463).

  - s390/kernel: make user-access pagetable walk code huge
    page aware (bnc#781485,LTC#85455).

XEN :

  - xen/netback: fix netbk_count_requests().

  - xen: properly bound buffer access when parsing
    cpu/availability.

  - xen/scsiback/usbback: move cond_resched() invocations to
    proper place.

  - xen/pciback: properly clean up after calling
    pcistub_device_find().

  - xen: add further backward-compatibility configure
    options.

  - xen/PCI: suppress bogus warning on old hypervisors.

  - xenbus: fix overflow check in xenbus_dev_write().

  - xen/x86: do not corrupt %eip when returning from a
    signal handler. Other :

  - kernel: Restrict clearing TIF_SIGPENDING. (bnc#742111)

  - kernel: recalc_sigpending_tsk fixes. (bnc#742111)

  - xfs: Do not reclaim new inodes in xfs_sync_inodes().
    (bnc#770980)

  - jbd: Avoid BUG_ON when checkpoint stalls. (bnc#795335)

  - reiserfs: Fix int overflow while calculating free space.
    (bnc#795075)

  - cifs: clarify the meaning of tcpStatus == CifsGood.
    (bnc#769093)

  - cifs: do not allow cifs_reconnect to exit with NULL
    socket pointer. (bnc#769093)

  - cifs: switch to seq_files. (bnc#776370)

  - scsi: fix check of PQ and PDT bits for WLUNs.
    (bnc#765687)

  - hugetlb: preserve hugetlb pte dirty state. (bnc#790236)

  - poll: enforce RLIMIT_NOFILE in poll(). (bnc#787272)

  - proc: fix ->open less usage due to ->proc_fops flip.
    (bnc#776370)

  - rpm/kernel-binary.spec.in: Ignore kabi errors if
    %%ignore_kabi_badness is defined. This is used in the
    Kernel:* projects in the OBS."
