Security Advisory - RHSA-2005:535-06
------------------------------------------------------------------------------
Summary:
Moderate: sudo security update

An updated sudo package is available that fixes a race condition in sudo's
pathname validation.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description:
The sudo (superuser do) utility allows system administrators to give
certain users the ability to run commands as root with logging.

A race condition bug was found in the way sudo handles pathnames. It is
possible that a local user with limited sudo access could create
a race condition that would allow the execution of arbitrary commands as
the root user. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-1993 to this issue.

Users of sudo should update to this updated package, which contains a
backported patch and is not vulnerable to this issue.
