SuSE 11.1 Security Update : Linux kernel (SAT Patch Numbers 5031 / 5055)

Medium Nessus Plugin ID 57109

Synopsis

The remote SuSE 11 host is missing one or more security updates.

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)

Solution

Apply SAT patch number 5031 / 5055 as appropriate.
