Product:           Red Hat HPC Solution
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1141.html

=====================================================================

1. Summary:

Updated nagios packages that fix one security issue are now available for
the Red Hat HPC Solution.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat HPC Solution for RHEL 5 Server - x86_64

3. Description:

Nagios is a program that can monitor hosts and services on your network. It
can send email or page alerts when problems arise and when problems are
resolved.

A shell command injection flaw was discovered in the statuswml.cgi CGI
script used by Nagios. A remote attacker able to access Nagios web pages
could use this flaw to run arbitrary commands with the privileges of the
web server user (apache). (CVE-2009-2288)

Note: Successful authentication is required to access Nagios web pages. In
the Red Hat HPC Solution, configuration for Nagios is provided by the
kusu-nagios-config package, which creates a user with a fixed, default
password during installation. It is recommended to change this default
password, or restrict access to Nagios web pages based on a client's IP
address as is appropriate for your environment.

Users of nagios should upgrade to these updated packages, which contain a
backported patch to correct this issue.

4. Solution:

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

This update is available via 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

5. Bugs fixed (http://bugzilla.redhat.com/):
