This update has been rated as having important security impact by the
Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux
This update fixes the following security issues :
* a flaw was found in each of the following Intel PRO/1000 Linux
drivers in the Linux kernel: e1000 and e1000e. A remote attacker using
packets larger than the MTU could bypass the existing fragment check,
resulting in partial, invalid frames being passed to the network
stack. These flaws could also possibly be used to trigger a remote
denial of service. (CVE-2009-4536, CVE-2009-4538, Important)
* a flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. Receiving overly-long frames with a certain revision of the
network cards supported by this driver could possibly result in a
remote denial of service. (CVE-2009-4537, Important)
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
