=====================================================================
1. Summary:

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

3. Description:
The tog-pegasus packages provide OpenPegasus Web-Based Enterprise
Management (WBEM) services. WBEM is a platform and resource independent
DMTF standard that defines a common information model, and communication
protocol for monitoring and controlling resources.
During a security audit, a stack buffer overflow flaw was found in the PAM
authentication code in the OpenPegasus CIM management server. An
unauthenticated remote user could trigger this flaw and potentially execute
arbitrary code with root privileges. (CVE-2008-0003)
Note that the tog-pegasus packages are not installed by default on Red Hat
Enterprise Linux. The Red Hat Security Response Team believes that it would
be hard to remotely exploit this issue to execute arbitrary code, due to
the default SELinux targeted policy on Red Hat Enterprise Linux 4 and 5,
and the SELinux memory protection tests enabled by default on Red Hat
Enterprise Linux 5.
Users of tog-pegasus should upgrade to these updated packages, which
contain a backported patch to resolve this issue. After installing the
updated packages the tog-pegasus service should be restarted.
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/FAQ_58_10188
5. Bugs fixed (http://bugzilla.redhat.com/):
