Posted on: 10/28/2005 11:12 PM

A new sudo vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-213-1 October 28, 2005
sudo vulnerability
CVE-2005-2959
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

sudo

The problem can be corrected by upgrading the affected package to
version 1.6.7p5-1ubuntu4.3 (for Ubuntu 4.10), 1.6.8p5-1ubuntu2.2 (for
Ubuntu 5.04), or 1.6.8p9-2ubuntu2.1 (for Ubuntu 5.10). In general, a
standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Tavis Ormandy discovered a privilege escalation vulnerability in sudo.
On executing shell scripts with sudo, the "P4" and "SHELLOPTS"
environment variables were not cleaned properly. If sudo is set up to
grant limited sudo privileges to normal users this could be exploited
to run arbitrary commands as the target user.
