6.8 - RHSA-2008:1001

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. 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.
