                   Red Hat Security Advisory

Synopsis:          Moderate: Red Hat Enterprise MRG Grid 2.0 security, bug fix
and enhancement update
Advisory ID:       RHSA-2011:1249-01
Product:           Red Hat Enterprise MRG for RHEL-5
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2011-1249.html
Issue date:        2011-09-07
CVE Names:         CVE-2011-2925 
=====================================================================

1. Summary:

Updated Grid component packages that fix one security issue, multiple bugs,
and add various enhancements are now available for Red Hat Enterprise MRG
2.0 for Red Hat Enterprise Linux 5.

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.

2. Relevant releases/architectures:

MRG Grid Execute Node for RHEL 5 Server v.2 - i386, noarch, x86_64

MRG Management for RHEL 5 Server v.2 - noarch

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 flaw was discovered in Cumin where it would log broker authentication
credentials to the Cumin log file. A local user exploiting this flaw could
connect to the broker outside of Cumin's control and perform certain
operations such as scheduling jobs, setting attributes on jobs, as well as
holding, releasing or removing jobs. The user could also use this to,
depending on the defined ACLs of the broker, manipulate message queues and
other privileged operations. (CVE-2011-2925)

In addition, these updated packages for Red Hat Enterprise Linux 5 provide
numerous bug fixes and enhancements for the Grid component of MRG. Some of
the most important enhancements include:

* Expanded support of EC2 features, including EBS and VPC.

* Improved negotiation performance.

* Reduced shadow memory usage.

* Integrated configuration and management experience, including real-time
monitoring, diagnostics, and configuration templates.

Release Notes:

* When MRG Grid ran on a node with multiple network interfaces, it tried to
estimate the correct interface for its communications with the remaining
MRG Grid nodes. As a consequence, the node could have failed to communicate
with other parts of MRG Grid correctly if the wrong interface had been
chosen. As a workaround to this issue, MRG Grid can be forced to use a
specific network interface by setting the NETWORK_INTERFACE parameter to
the IP address of that interface. To determine which interface was used by
MRG Grid when it fails to communicate with other parts of the grid, include
the D_HOSTNAME variable in the logging configuration of the corresponding
daemon. (BZ#728285)

* The remote configuration database requires an update to include changes
for MRG Grid version 2.0.1. But the database snapshot provided with MRG
only contains a basic configuration, and thus loading the database snapshot
would replace the existing pool configuration. To solve this issue, the
upgrade-wallaby-db tool which upgrades an existing deployment's database
has to be used. This tool can be downloaded from the following page:
https://access.redhat.com/kb/docs/DOC-58404

* With this update, the Elastic Compute Cloud Grid ASCII Helper Protocol
(EC2 GAHP) is preferred over AMAZON GAHP. The condor-ec2-enhanced-hooks
package has been updated to detect the correct GAHP for the EC2 Enhanced
feature based upon what GAHPs are available on the scheduler. To ensure
that jobs are routed to the proper resources, the 'set_gridresource =
"amazon"; \' setting should be removed from all existing EC2 Enhanced
routes in a MRG Grid's configuration. (BZ#688717)

Space precludes documenting all of these changes in this advisory. Refer to
the Red Hat Enterprise MRG 2.0 Technical Notes document for information on
these changes:

https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/2.0/html/Technica
l_Notes/index.html

All users of the Grid capabilities of Red Hat Enterprise MRG 2.0 are
advised to upgrade to these updated packages, which resolve the issues and
add the enhancements noted in the Red Hat Enterprise MRG 2.0 Technical
Notes.
