Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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.
Update the affected packages.
