Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-661-1 (linux)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to linux announced via advisory USN-661-1. A security issue affects the following Ubuntu releases: Ubuntu 8.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. Details follow: 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. Solution: The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.10: linux-image-2.6.27-7-generic 2.6.27-7.15 linux-image-2.6.27-7-server 2.6.27-7.15 linux-image-2.6.27-7-virtual 2.6.27-7.15 procps 1:3.2.7-9ubuntu2.1 After a standard system upgrade you need to reboot your computer to effect the necessary changes. http://www.securityspace.com/smysecure/catid.html?in=USN-661-1 Risk factor : High
