RHSA-2014:0440 - Security Advisory

Topic

Updated 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.

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.

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.
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.
