Synopsis

The remote Red Hat host is missing a security update.

Description

An updated cobbler package that fixes one security issue is now available for Red Hat Network Satellite Server 5.3.

The Red Hat Security Response Team has rated this update as having important 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.

Cobbler is a network install server. Cobbler supports PXE, virtualized installs, and re-installing existing Linux machines. Cheetah is a template engine used by Cobbler to process kickstart files.

A code injection flaw was found in the way Cobbler processed templates for kickstart files. A remote, authenticated user, that has the Configuration Administrator role privilege, could use this flaw to create a specially crafted kickstart template file containing embedded Python code that could, when processed by Cheetah, execute arbitrary code with root privileges on the Red Hat Network Satellite Server.
(CVE-2010-2235)

Red Hat would like to thank Doug Knight of the University of Alaska for reporting this issue.

Users of Red Hat Network Satellite Server 5.3 are advised to upgrade to this updated cobbler package, which contains backported patches to correct this issue. Red Hat Network Satellite Server must be restarted ('/usr/sbin/rhn-satellite restart') for this update to take effect.

Solution

Update the affected cobbler package.
