"These updated packages fix the following security issue :

  - a possible kernel memory leak was found in the Linux
    kernel Simple Internet Transition (SIT) INET6
    implementation. This could allow a local unprivileged
    user to cause a denial of service. (CVE-2008-2136,
    Important)

As well, these updated packages fix the following bugs :

  - a possible kernel hang on hugemem systems, due to a bug
    in NFS, which may have caused systems to become
    unresponsive, has been resolved.

  - an inappropriate exit condition occurred in the
    architecture-specific 'mmap()' realization, which fell
    into an infinite loop under certain conditions. On
    64-bit systems, this issue may have manifested itself to
    users as a soft lockup, or process hangs.

  - due to a bug in hardware initialization in the
    'ohci_hcd' kernel module, the kernel may have failed
    with a NULL pointer dereference. On 64-bit PowerPC
    systems, this may have caused booting to fail, and drop
    to xmon. On other platforms, a kernel oops occurred.

  - due to insufficient locks in task termination code, a
    panic may have occurred in the 'sys_times()' system call
    on SMP machines."
