RHEL 5 : kernel (RHSA-2010:0019)
Critical Nessus Plugin ID 43820
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated kernel packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.
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 operating 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 not properly validated in the ipv6_hop_jumbo() function. This could possibly lead 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 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.
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.
SolutionUpdate the affected packages.
