"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."
