3. Description:

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 buffer over-read flaw was found in the way MongoDB handled BSON data. A database user permitted to insert BSON data into a MongoDB server could use this flaw to read server memory, potentially disclosing sensitive data. (CVE-2012-6619)

Note: This update addresses CVE-2012-6619 by enabling the "--objcheck" option in the /etc/mongodb.conf file. If you have edited this file, the updated version will be stored as /etc/mongodb.conf.rpmnew, and you will need to merge the changes into /etc/mongodb.conf manually.

It was found that MRG Management Console (cumin) used the crypt(3) DES-based hash function to hash passwords. DES-based hashing has known weaknesses that allow an attacker to recover plain text passwords from hashes. An attacker able to compromise a cumin user database could potentially use this flaw to recover plain text passwords from the password hashes stored in that database. (CVE-2013-6445)

Note: In deployments where user account information is stored in a database managed by cumin, it is recommended that users change their passwords after this update is applied.
