Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated Grid component packages that fix one security issue, multiple bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.4 for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate 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.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers.

MRG Grid provides high-throughput computing and enables enterprises to achieve higher peak computing capacity as well as improved infrastructure utilization by leveraging their existing technology to build high performance grids. MRG Grid provides a job-queueing mechanism, scheduling policy, and a priority scheme, as well as resource monitoring and resource management. Users submit their jobs to MRG Grid, where they are placed into a queue. MRG Grid then chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion.

A denial of service flaw was found in the way cumin, a web management console for MRG, processed certain Ajax update queries. A remote attacker could use this flaw to issue a specially crafted HTTP request, causing excessive use of CPU time and memory on the system.
(CVE-2013-4284)

The CVE-2013-4284 issue was discovered by Tomas Novacik of Red Hat.

These updated packages for Red Hat Enterprise Linux 6 provide numerous enhancements and bug fixes for the Grid component of MRG. Some of the most important enhancements include :

* Improved resource utilization with scheduler driven slot partitioning

* Enhanced integration with existing user & group management technology, specifically allowing group and netgroup specifications in HTCondor security policies

* Addition of global job priorities, allowing for priority to span scaled-out queues

* Reduced memory utilization per running job

Space precludes documenting all of these changes in this advisory.
Refer to the Red Hat Enterprise MRG 2 Technical Notes document, available shortly from the link in the References section, for information on these changes.

All users of the Grid capabilities of Red Hat Enterprise MRG are advised to upgrade to these updated packages, which correct this issue, and fix the bugs and add the enhancements noted in the Red Hat Enterprise MRG 2 Technical Notes.

Solution
