CentOS 5 : sudo (CESA-2010:0475)

medium Nessus Plugin ID 47032

Language:

Synopsis

The remote CentOS 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 moderate 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 the presence of duplicated environment variables. A local user authorized to run commands using sudo could use this flaw to set additional values for the environment variables set by sudo, which could result in those values being used by the executed command instead of the values set by sudo. This could possibly lead to certain intended restrictions being bypassed, such as the secure_path setting. (CVE-2010-1646)

Red Hat would like to thank Anders Kaseorg and Evan Broder of Ksplice, Inc. for responsibly reporting this issue.

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

Solution

Update the affected sudo package.
