Ubuntu 8.10 : linux regression (USN-661-1)
high Nessus Plugin ID 37570
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
