Description

This kernel update for openSUSE 10.3 fixes some bugs and several security problems.

The following security issues are fixed: CVE-2009-2692: A missing NULL pointer check in the socket sendpage function can be used by local attackers to gain root privileges.

CVE-2009-2406: 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-2009-2407: 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.

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.

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

CVE-2009-0676: A memory disclosure via the SO_BSDCOMPAT socket option was fixed.

CVE-2009-1630: The nfs_permission function in fs/nfs/dir.c in the NFS client implementation when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.

random: make get_random_int() was made more random to enhance ASLR protection.
