RHEL 5 : sudo (RHSA-2010:0675)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated sudo package that fixes one security issue is now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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

A flaw was found in the way sudo handled Runas specifications
containing both a user and a group list. If a local user were
authorized by the sudoers file to perform their sudo commands with the
privileges of a specified user and group, they could use this flaw to
run those commands with the privileges of either an arbitrary user or
group on the system. (CVE-2010-2956)

Red Hat would like to thank Markus Wuethrich of Swiss Post -
PostFinance for reporting this issue.

Users of sudo should upgrade to this updated package, which contains a
backported patch to correct this issue.
