RHEL 5 : sudo (RHSA-2009:0267)

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated sudo package to fix a security issue is now available for
Red Hat Enterprise Linux 5.

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

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

A flaw was discovered in a way sudo handled group specifications in
'run as' lists in the sudoers configuration file. If sudo
configuration allowed a user to run commands as any user of some group
and the user was also a member of that group, sudo incorrectly allowed
them to run defined commands with the privileges of any system user.
This gave the user unintended privileges. (CVE-2009-0034)

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