RHSA-2010:0019: Important: kernel security update

The kernel packages contain the Linux kernel, the core of any Linuxoperating system.This update fixes the following security issues: a flaw was found in the IPv6 Extension Header (EH) handling implementation in the Linux kernel. The skb->dst data structure was notproperly validated in the ipv6hopjumbo() function. This could possiblylead to a remote denial of service. (CVE-2007-4567, Important) 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 largerthan the MTU could bypass the existing fragment check, resulting inpartial, invalid frames being passed to the network stack. These flawscould 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 thisdriver could possibly result in a remote denial of service. (CVE-2009-4537,Important)Users should upgrade to these updated packages, which contain backportedpatches to correct these issues. The system must be rebooted for thisupdate to take effect.
