RHSA-2008:1001 - Security Advisory

Topic

Updated tog-pegasus packages that fix security issues are now available
for Red Hat Enterprise Linux 5.

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

Description

The tog-pegasus packages provide OpenPegasus Web-Based Enterprise
Management (WBEM) services. WBEM is a platform and resource independent
Distributed Management Task Force (DMTF) standard that defines a common
information model and communication protocol for monitoring and controlling
resources.

Red Hat defines additional security enhancements for OpenGroup Pegasus WBEM
services in addition to those defined by the upstream OpenGroup Pegasus
release. For details regarding these enhancements, refer to the file
"README.RedHat.Security", included in the Red Hat tog-pegasus package.

After re-basing to version 2.7.0 of the OpenGroup Pegasus code, these
additional security enhancements were no longer being applied. As a
consequence, access to OpenPegasus WBEM services was not restricted to the
dedicated users as described in README.RedHat.Security. An attacker able to
authenticate using a valid user account could use this flaw to send
requests to WBEM services. (CVE-2008-4313)

Note: default SELinux policy prevents tog-pegasus from modifying system
files. This flaw's impact depends on whether or not tog-pegasus is confined
by SELinux, and on any additional CMPI providers installed and enabled on a
particular system.

Failed authentication attempts against the OpenPegasus CIM server were not
logged to the system log as documented in README.RedHat.Security. An
attacker could use this flaw to perform password guessing attacks against a
user account without leaving traces in the system log. (CVE-2008-4315)

All tog-pegasus users are advised to upgrade to these updated packages,
which contain patches to correct these issues.
