RHEL 6 : MRG (RHSA-2014:0440)
Medium Nessus Plugin ID 76675
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated Grid component packages that fix two security issues, multiple bugs, and provide several enhancements are now available for Red Hat Enterprise MRG 2.5 for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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 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.
The CVE-2013-6445 issue was discovered by Tomas Novacik 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. 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 these issues and add these enhancements.
SolutionUpdate the affected packages.
