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
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
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.
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.
The CVE-2013-6445 issue was discovered by Tomáš Nováčik of the Red Hat MRG
Quality Engineering team.
These updated packages for Red Hat Enterprise Linux 6 also provide numerous
bug fixes and enhancements for the Grid component of Red Hat Enterprise
MRG. Space precludes documenting all of these changes in this advisory.
