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.

[Updated 28 July 2010] The CVE-2010-1871 description has been updated
to reflect that an attacker does not need to be authenticated to
exploit this issue. No changes have been made to the packages.

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

An input sanitization flaw was found in the way JBoss Seam processed
certain parametrized JBoss Expression Language (EL) expressions. A
remote attacker could use this flaw to execute arbitrary code via a
URL, containing appended, specially crafted expression language
parameters, provided to certain applications based on the JBoss Seam
framework. Note: A properly configured and enabled Java Security
Manager would prevent exploitation of this flaw. (CVE-2010-1871)

Red Hat would like to thank Meder Kydyraliev of the Google Security
Team for responsibly reporting this issue.

Users of jboss-seam2 should upgrade to these updated packages, which
contain a backported patch to correct this issue. The JBoss server
process must be restarted for this update to take effect.
