"This update fixes the following security issues :

  - A flaw was found in the Linux kernel's garbage collector
    for AF_UNIX sockets. A local, unprivileged user could
    use this flaw to trigger a denial of service
    (out-of-memory condition). (CVE-2010-4249, Moderate)

  - A flaw was found in the Linux kernel's networking
    subsystem. If the number of packets received exceeded
    the receiver's buffer limit, they were queued in a
    backlog, consuming memory, instead of being discarded. A
    remote attacker could abuse this flaw to cause a denial
    of service (out-of-memory condition). (CVE-2010-4251,
    Moderate)

  - A missing initialization flaw was found in the
    ethtool_get_regs() function in the Linux kernel's
    ethtool IOCTL handler. A local user who has the
    CAP_NET_ADMIN capability could use this flaw to cause an
    information leak. (CVE-2010-4655, Low)

This update also fixes several bugs.

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

NOTE: For those who have tested our updated openafs package for SL5,
you will need to enable the sl-testing repository to properly do this
update. We apologize for this. yum --enablerepo=sl-testing update
kernel\* Again, this is only for those who have updated openafs to
1.4.14"
