"This update fixes the following security issues :

  - A divide-by-zero flaw was found in the
    tcp_select_initial_window() function in the Linux
    kernel's TCP/IP protocol suite implementation. A local,
    unprivileged user could use this flaw to trigger a
    denial of service by calling setsockopt() with certain
    options. (CVE-2010-4165, Moderate)

  - A use-after-free flaw in the mprotect() system call in
    the Linux kernel could allow a local, unprivileged user
    to cause a local denial of service. (CVE-2010-4169,
    Moderate)

  - A flaw was found in the Linux kernel execve() system
    call implementation. A local, unprivileged user could
    cause large amounts of memory to be allocated but not
    visible to the OOM (Out of Memory) killer, triggering a
    denial of service. (CVE-2010-4243, Moderate)

This update also fixes several bugs and adds two enhancements.

The system must be rebooted for this update to take effect."
