SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionCVE-2007-4567 kernel: ipv6_hop_jumbo remote system crash
CVE-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 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. (CVE-2009-4537, Important)
The system must be rebooted for this update to take effect.
Note1: Due to the fuse kernel module now being part of the kernel, we are updating fuse on the older releases to match the fuse that was released by The Upstream Vendor.
Note2: xfs is now part of the kernel in x86_64. Because of this there is no kernel-module-xfs for x86_64.
Note3: ipw3945 support has been changed to iwlwifi3945 in SL 54, and is in the kernel. Because of this there is no kernel-module-ipw3945 for SL54.
Note4: Support for the Atheros chipset in now in the kernel. We are not sure if the infrastructure is in place for SL 50-53, so we are still providing the madwifi kernel modules for SL 50-53.
SolutionUpdate the affected packages.
