   An update that solves 7 vulnerabilities and has two fixes
   is now available.

Description:


   The openSUSE 12.1 kernel was updated to fix a severe
   secrutiy issue and various bugs.

   Security issues fixed: CVE-2013-2094: The perf_swevent_init
   function in kernel/events/core.c in the Linux kernel used
   an incorrect integer data type, which allowed local users
   to gain privileges via a crafted perf_event_open system
   call.

   CVE-2013-1774: The chase_port function in
   drivers/usb/serial/io_ti.c in the Linux kernel allowed
   local users to cause a denial of service (NULL pointer
   dereference and system crash) via an attempted /dev/ttyUSB
   read or write operation on a disconnected Edgeport USB
   serial converter.

   CVE-2013-1928: The do_video_set_spu_palette function in
   fs/compat_ioctl.c in the Linux kernel lacked a certain
   error check, which might have allowed local users to obtain
   sensitive information from kernel stack memory via a
   crafted VIDEO_SET_SPU_PALETTE ioctl call on a /dev/dvb
   device.

   CVE-2013-1796: The kvm_set_msr_common function in
   arch/x86/kvm/x86.c in the Linux kernel did not ensure a
   required time_page alignment during an MSR_KVM_SYSTEM_TIME
   operation, which allowed guest OS users to cause a denial
   of service (buffer overflow and host OS memory corruption)
   or possibly have unspecified other impact via a crafted
   application.

   CVE-2013-1797: Use-after-free vulnerability in
   arch/x86/kvm/x86.c in the Linux kernel allowed guest OS
   users to cause a denial of service (host OS memory
   corruption) or possibly have unspecified other impact via a
   crafted application that triggers use of a guest physical
   address (GPA) in (1) movable or (2) removable memory during
   an MSR_KVM_SYSTEM_TIME kvm_set_msr_common operation.

   CVE-2013-1798: The ioapic_read_indirect function in
   virt/kvm/ioapic.c in the Linux kernel did not properly
   handle a certain combination of invalid IOAPIC_REG_SELECT
   and IOAPIC_REG_WINDOW operations, which allowed guest OS
   users to obtain sensitive information from host OS memory
   or cause a denial of service (host OS OOPS) via a crafted
   application.

   CVE-2013-1767: Use-after-free vulnerability in the
   shmem_remount_fs function in mm/shmem.c in the Linux kernel
   allowed local users to gain privileges or cause a denial of
   service (system crash) by remounting a tmpfs filesystem
   without specifying a required mpol (aka mempolicy) mount
   option.

   CVE-2013-0913: Integer overflow in
   drivers/gpu/drm/i915/i915_gem_execbuffer.c in the i915
   driver in the Direct Rendering Manager (DRM) subsystem in
   the Linux kernel allowed local users to cause a denial of
   service (heap-based buffer overflow) or possibly have
   unspecified other impact via a crafted application that
   triggers many relocation copies, and potentially leads to a
   race condition.

   Bugs fixed:
   - qlge: fix dma map leak when the last chunk is not
   allocated (bnc#819519).

   - TTY: fix atime/mtime regression (bnc#815745).

   - fs/compat_ioctl.c: VIDEO_SET_SPU_PALETTE missing error
   check (bnc#813735).

   - USB: io_ti: Fix NULL dereference in chase_port()
   (bnc#806976, CVE-2013-1774).

   - KVM: Convert MSR_KVM_SYSTEM_TIME to use
   gfn_to_hva_cache_init (bnc#806980 CVE-2013-1797).
   - KVM: Fix bounds checking in ioapic indirect register read
   (bnc#806980 CVE-2013-1798).
   - KVM: Fix for buffer overflow in handling of
   MSR_KVM_SYSTEM_TIME (bnc#806980 CVE-2013-1796).
   - kabi/severities: Allow kvm module abi changes - modules
   are self consistent

   - loopdev: fix a deadlock (bnc#809748).
   - block: use i_size_write() in bd_set_size() (bnc#809748).

   - drm/i915: bounds check execbuffer relocation count
   (bnc#808829,CVE-2013-0913).

   - tmpfs: fix use-after-free of mempolicy object
   (bnc#806138, CVE-2013-1767).
