CentOS 5 : sudo (CESA-2014:0266)

medium Nessus Plugin ID 72910

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 its blacklist of environment variables. When the 'env_reset' option was disabled, a user permitted to run certain commands via sudo could use this flaw to run such a command with one of the blacklisted environment variables set, allowing them to run an arbitrary command with the target user's privileges. (CVE-2014-0106)

Note: This issue does not affect the default configuration of the sudo package as shipped with Red Hat Enterprise Linux 5.

Red Hat would like to thank Todd C. Miller for reporting this issue.
Upstream acknowledges Sebastien Macke as the original reporter.

All sudo users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected sudo package.
