Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
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 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.
