RHEL 5 : cobbler (RHSA-2010:0775)

critical Nessus Plugin ID 50009

Synopsis

The remote Red Hat host is missing a security update for cobbler.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2010:0775 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL cobbler package based on the guidance in RHSA-2010:0775.
