1. Summary:

Updated Grid component packages that fix several security issues, add
various enhancements and fix multiple bugs are now available for Red Hat
Enterprise MRG 2 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.

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.

A number of unprotected resources (web pages, export functionality, image
viewing) were found in Cumin. An unauthenticated user could bypass intended
access restrictions, resulting in information disclosure. (CVE-2012-2680)

Cumin could generate weak session keys, potentially allowing remote
attackers to predict session keys and obtain unauthorized access to Cumin.
(CVE-2012-2681)

Multiple cross-site scripting flaws in Cumin could allow remote attackersto inject arbitrary web script on a web page displayed by Cumin.
(CVE-2012-2683)

An SQL injection flaw in Cumin could allow remote attackers to manipulate
the contents of the back-end database via a specially-crafted URL.
(CVE-2012-2684)

When Cumin handled image requests, clients could request images of
arbitrary sizes. This could result in large memory allocations on the Cumin
server, leading to an out-of-memory condition. (CVE-2012-2685)

Cumin did not protect against Cross-Site Request Forgery attacks. If an
attacker could trick a user, who was logged into the Cumin web interface,
into visiting a specially-crafted web page, it could lead to unauthorized
command execution in the Cumin web interface with the privileges of the
logged-in user. (CVE-2012-2734)

A session fixation flaw was found in Cumin. An authenticated user able to
pre-set the Cumin session cookie in a victim's browser could possibly use
this flaw to steal the victim's session after they log into Cumin.
(CVE-2012-2735)

It was found that authenticated users could send a specially-crafted HTTP
POST request to Cumin that would cause it to submit a job attribute change
to Condor. This could be used to change internal Condor attributes,
including the Owner attribute, which could allow Cumin users to elevate
their privileges. (CVE-2012-3459)

It was discovered that Condor's file system authentication challenge
accepted directories with weak permissions (for example, world readable,
writable and executable permissions). If a user created a directory with
such permissions, a local attacker could rename it, allowing them to
execute jobs with the privileges of the victim user. (CVE-2012-3492)

It was discovered that Condor exposed private information in the data in
the ClassAds format served by condor_startd. An unauthenticated user able
to connect to condor_startd's port could request a ClassAd for a running
job, provided they could guess or brute-force the PID of the job. This
could expose the ClaimId which, if obtained, could be used to control the
job as well as start new jobs on the system. (CVE-2012-3493)

It was discovered that the ability to abort a job in Condor only required
WRITE authorization, instead of a combination of WRITE authorization and
job ownership. This could allow an authenticated attacker to bypass
intended restrictions and abort any idle job on the system. (CVE-2012-3491)

The above issues were discovered by Florian Weimer of the Red Hat Product
Security Team.

This update also provides defense in depth patches for Condor. (BZ#848212,
BZ#835592, BZ#841173, BZ#843476)

These updated packages for Red Hat Enterprise Linux 6 provide numerous
enhancements and bug fixes for the Grid component of MRG. Some highlights
include:

* Integration with Red Hat Enterprise Virtualization Manager via Deltacloud
* Role enforcement in Cumin
* Cumin authentication integration with LDAP
* Enhanced Red Hat HA integration managing multiple-schedulers nodes
* Generic local resource limits for partitionable slots
* Concurrency limit groups

Space precludes documenting all of these changes in this advisory. Refer to
the Red Hat Enterprise MRG 2 Technical Notes document, linked to in the
References section, for information on these changes.

4. Solution:

All users of the Grid capabilities of Red Hat Enterprise MRG 2 are advised
to upgrade to these updated packages, which resolve the issues and add the
enhancements noted in the Red Hat Enterprise MRG 2 Technical Notes. Condor
and Cumin must be restarted for this update to take effect.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
