Synopsis
========

Multiple vulnerabilities have been found in sudo, the worst of which
could result in privilege escalation.

Background
==========

sudo (su "do") allows a system administrator to delegate authority to
give certain users (or groups of users) the ability to run some (or
all) commands as root or another user while providing an audit trail of
the commands and their arguments.
