Subject: [USN-722-1] sudo vulnerability
===========================================================
Ubuntu Security Notice USN-722-1 February 17, 2009
sudo vulnerability
CVE-2009-0034
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 8.04 LTS
Ubuntu 8.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
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.
Details follow:
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.
Updated packages for Ubuntu 8.04 LTS:
