Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : openssh vulnerability (USN-566-1)

high Nessus Plugin ID 29922

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Jan Pechanec discovered that ssh would forward trusted X11 cookies when untrusted cookie generation failed. This could lead to unintended privileges being forwarded to a remote host.

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

Update the affected packages.
