1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Network Satellite Server 5.3 (RHEL v.4) - i386, s390, s390x, x86_64
Red Hat Network Satellite Server 5.3 (RHEL v.5) - i386, s390x, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
