Description

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.29 fixing various bugs and security issues.

The following security issues were fixed :

  • A missing NULL pointer check in the socket sendpage function can be used by local attackers to gain root privileges. (CVE-2009-2692)

  • A kernel stack overflow when mounting eCryptfs filesystems in parse_tag_11_packet() was fixed. Code execution might be possible of ecryptfs is in use. (CVE-2009-2406)

  • A kernel heap overflow when mounting eCryptfs filesystems in parse_tag_3_packet() was fixed. Code execution might be possible of ecryptfs is in use. (CVE-2009-2407)

The compiler option -fno-delete-null-pointer-checks was added to the kernel build, and the -fwrapv compiler option usage was fixed to be used everywhere. This works around the compiler removing checks too aggressively.

  • A crash in the r8169 driver when receiving large packets was fixed. This is probably exploitable only in the local network. (CVE-2009-1389)

No CVE yet: A sigaltstack kernel memory disclosure was fixed.

The NULL page protection using mmap_min_addr was enabled (was disabled before).

This update also adds the Microsoft Hyper-V drivers from upstream.

Additionaly a lot of bugs were fixed.
