Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated jboss-seam2 packages that fix one security issue are now
available for JBoss Enterprise Application Platform 4.3 for Red Hat
Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having
important 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.

The JBoss Seam 2 framework is an application framework for building
web applications in Java.

It was found that the fix for CVE-2011-1484 was incomplete: JBoss Seam
2 did not block access to all malicious JBoss Expression Language (EL)
constructs in page exception handling, allowing arbitrary Java methods
to be executed. A remote attacker could use this flaw to execute
arbitrary code via a specially crafted URL provided to certain
applications based on the JBoss Seam 2 framework. Note: A properly
configured and enabled Java Security Manager would prevent
exploitation of this flaw. (CVE-2011-2196)

Red Hat would like to thank the ObjectWorks+ Development Team at
Nomura Research Institute for reporting this issue.

Users of jboss-seam2 should upgrade to these updated packages, which
correct this issue. Manual action is required for this update to take
effect. Refer to the Solution section for details.
