Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2012:1081 :

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.
