Scientific Linux Security Update : kernel on SL4.x i386/x86_64
Critical Nessus Plugin ID 60716
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionCVE-2009-4537 kernel: r8169 issue reported at 26c3
CVE-2009-4538 kernel: e1000e frame fragment issue
CVE-2009-4536 kernel: e1000 issue reported at 26c3
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)
The system must be rebooted for this update to take effect.
SolutionUpdate the affected packages.
