SynopsisThe remote CentOS host is missing a security update.
DescriptionAn 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.
The RHBA-2010:0212 sudo update released as part of Red Hat Enterprise Linux 5.5 added the ability to change the value of the ignore_dot option in the '/etc/sudoers' configuration file. This ability introduced a regression in the upstream fix for CVE-2010-0426. In configurations where the ignore_dot option was set to off (the default is on for the Red Hat Enterprise Linux 5 sudo package), a local user authorized to use the sudoedit pseudo-command could possibly run arbitrary commands with the privileges of the users sudoedit was authorized to run as. (CVE-2010-1163)
Red Hat would like to thank Todd C. Miller, the upstream sudo maintainer, for responsibly reporting this issue. Upstream acknowledges Valerio Costamagna as the original reporter.
Users of sudo should upgrade to this updated package, which contains a backported patch to correct this issue.
SolutionUpdate the affected sudo package.
