Summary
The remote host is missing an update to sudo announced via advisory USN-722-1.
Insight
Insight
Harald Koenig discovered that sudo did not correctly handle certain privilege changes when handling groups. If a local attacker belonged to a group included in a RunAs list in the /etc/sudoers file, that user could gain root privileges. This was not an issue for the default sudoers file shipped with Ubuntu.
Solution
Solution
The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: sudo 1.6.9p10-1ubuntu3.4 Ubuntu 8.10: sudo 1.6.9p17-1ubuntu2.1 In general, a standard system upgrade is sufficient to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-722-1
