Ubuntu 7.04 : xen-3.0 vulnerability (USN-527-1)

medium Nessus Plugin ID 28132

Synopsis

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

Description

Joris van Rantwijk discovered that the Xen host did not correctly validate the contents of a Xen guests's grug.conf file. Xen guest root users could exploit this to run arbitrary commands on the host when the guest system was rebooted.

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.
