3. Description:

Red Hat Enterprise MRG (Messaging, Realtime and Grid) is a real-time IT infrastructure for enterprise computing. MRG Messaging implements the Advanced Message Queuing Protocol (AMQP) standard, adding persistence options, kernel optimizations, and operating system services.

The Management Console Installation Guide for Red Hat Enterprise MRG 1.3 instructed administrators to configure Condor to allow the MRG Management Console (cumin) to submit jobs on behalf of a user. This configuration facilitated a trust relationship between cumin and the Condor QMF plug-ins; however, there was inadequate access control on the trusted channel, allowing anyone able to publish to a broker to submit jobs to run as any other user (except root, as Condor does not run jobs as root). (CVE-2010-4179)

These updated packages also include multiple bug fixes. Users are directed to the Red Hat Enterprise MRG 1.3 Technical Notes for information on these changes: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/1/html/Technical_N otes/RHSA-2010-0922.html

All Red Hat Enterprise MRG users are advised to upgrade to these updated packages, which correct this issue and the issues noted in the Red Hat Enterprise MRG 1.3 Technical Notes. After installing the updated packages, Condor must be restarted for the update to take effect.

4. Solution:

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