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.
    (CVE-2009-1630)
