This updates the SUSE Linux Enterprise Server 9 kernel to fix various security issues and some bugs.

The following security bugs were fixed :

  - Incorrect buffer handling in the biarch-compat buffer     handling could be used by local attackers to gain root     privileges. This problem affects foremost x86_64, or     potentially other biarch platforms, like PowerPC and     S390x. (CVE-2010-3081)

(CVE-2010-2248)

Additionally a data corruption bug in s390 was fixed :

  - A race between /proc/pid/stat and fork in the S390     kernel could lead to data corruption.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-2492     Andre Osterhues reported an issue in the eCryptfs     subsystem. A buffer overflow condition may allow local     users to cause a denial of service or gain elevated     privileges.

  - CVE-2010-2954     Tavis Ormandy reported an issue in the irda subsystem     which may allow local users to cause a denial of service     via a NULL pointer dereference.

  - CVE-2010-3078     Dan Rosenberg discovered an issue in the XFS file system     that allows local users to read potentially sensitive     kernel memory.

  - CVE-2010-3080     Tavis Ormandy reported an issue in the ALSA sequencer     OSS emulation layer. Local users with sufficient     privileges to open /dev/sequencer (by default on Debian,     this is members of the 'audio' group) can cause a denial     of service via a NULL pointer dereference.

  - CVE-2010-3081     Ben Hawkes discovered an issue in the 32-bit     compatibility code for 64-bit systems. Local users can     gain elevated privileges due to insufficient checks in     compat_alloc_user_space allocations.
