"This patch updates the SUSE Linux Enterprise 10 SP2 kernel to fix
various bugs and some security issues.

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

(No cve yet) A information leak from using sigaltstack was fixed.

Enabled -fno-delete-null-pointer-checks to avoid optimizing away NULL
pointer checks and fixed Makefiles to make sure

-fwrapv is used everywhere. CVE-2009-1758: The hypervisor_callback
function in Xen allows guest user applications to cause a denial of
service (kernel oops) of the guest OS by triggering a segmentation
fault in 'certain address ranges.'

  - A crash on r8169 network cards when receiving large
    packets was fixed. (CVE-2009-1389)

  - The nfs_permission function in fs/nfs/dir.c in the NFS
    client implementation in the Linux kernel, 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.
