   An update that solves 6 vulnerabilities and has 23 fixes is
   now available.

Description:

   The SUSE Linux Enterprise 11 Service Pack 1 kernel was
   updated to 2.6.32.45 and fixes various bugs and security
   issues.

   Following security issues were fixed: CVE-2011-1776: Timo
   Warns reported an issue in the Linux implementation for
   GUID partitions. Users with physical access could gain
   access to sensitive kernel memory by adding a storage
   device with a specially crafted corrupted invalid partition
   table.

   CVE-2010-3881: The second part of this fix was not yet
   applied to our kernel: arch/x86/kvm/x86.c in the Linux
   kernel before 2.6.36.2 does not initialize certain
   structure members, which allows local users to obtain
   potentially sensitive information from kernel stack memory
   via read operations on the /dev/kvm device.

   CVE-2011-2495: The /proc/PID/io interface could be used by
   local attackers to gain information on other processes like
   number of password characters typed or similar.

   CVE-2011-2700: A small buffer overflow in the radio driver
   si4713-i2c was fixed that could potentially used by local
   attackers to crash the kernel or potentially execute code.

   CVE-2011-2909: A kernel information leak in the comedi
   driver from kernel to userspace was fixed.

   CVE-2011-2918: In the perf framework software event
   overflows could deadlock or delete an uninitialized timer.


Special Instructions and Notes:

   Please reboot the system after installing this update.
