RHSA-2010:0921 - Security Advisory

Topic

Updated Red Hat Enterprise MRG Messaging and Grid packages that fix one
security issue and several bugs are now available for Red Hat Enterprise
Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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_Notes/RHSA-2010-0921.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.
