Description

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

The following security issues have been fixed :

  • 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-2011-1776)

  • 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-2010-3881)

  • 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-2011-2495)

  • 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-2011-2700)

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

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