high Nessus Plugin ID 59982

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An updated sudo package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6.

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 the network matching code in sudo handled multiple IP networks listed in user specification configuration directives. A user, who is authorized to run commands with sudo on specific hosts, could use this flaw to bypass intended restrictions and run those commands on hosts not matched by any of the network specifications. (CVE-2012-2337)

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

Solution

Update the affected sudo and / or sudo-debuginfo packages.
