Ubuntu Update for Linux kernel vulnerabilities USN-661-1

Please Install the Updated Packages.

Version 2.6.27 of the Linux kernel changed the order of options in TCP headers. While this change was RFC-compliant, it was found that some old routers and consumer DSL modems would not route traffic for these systems when TCP timestamps were enabled. As a workaround, TCP timestamps were disabled via sysctl. This update restores the previous ordering of TCP options, and reenables TCP timestamps. We apologize for the inconvenience.
