"This update fixes a several security issues and various bugs in the
SUSE Linux Enterprise 10 SP 2 kernel.

The following security issues were fixed: CVE-2009-3547: A race
condition during pipe open could be used by local attackers to elevate
privileges.

  - On x86_64 systems a information leak of high register
    contents (upper 32bit) was fixed. (CVE-2009-2910)

  - The randomness of the ASLR methods used in the kernel
    was increased. (CVE-2009-3238)

  - A information leak from the kernel due to uninitialized
    memory in AGP handling was fixed. (CVE-2009-1192)

  - A signed comparison in the ax25 sockopt handler was
    fixed which could be used to crash the kernel or
    potentially execute code. (CVE-2009-2909)

  - The execve function in the Linux kernel did not properly
    clear the current->clear_child_tid pointer, which allows
    local users to cause a denial of service (memory
    corruption) or possibly gain privileges via a clone
    system call with CLONE_CHILD_SETTID or
    CLONE_CHILD_CLEARTID enabled, which is not properly
    handled during thread creation and exit. (CVE-2009-2848)

  - Fixed various sockethandler getname leaks, which could
    disclose memory previously used by the kernel or other
    userland processes to the local attacker.
    (CVE-2009-3002)

  - Multiple buffer overflows in the cifs subsystem in the
    Linux kernel allow remote CIFS servers to cause a denial
    of service (memory corruption) and possibly have
    unspecified other impact via (1) a malformed Unicode
    string, related to Unicode string area alignment in
    fs/cifs/sess.c; or (2) long Unicode characters, related
    to fs/cifs/cifssmb.c and the cifs_readdir function in
    fs/cifs/readdir.c. (CVE-2009-1633)
