"Updated tomcat7 packages that fix one security issue are now available
for JBoss Enterprise Web Server 2.0.0 for Red Hat Enterprise Linux 5
and 6.

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.

Apache Tomcat is a servlet container.

It was found that sending a request without a session identifier to a
protected resource could bypass the Cross-Site Request Forgery (CSRF)
prevention filter. A remote attacker could use this flaw to perform
CSRF attacks against applications that rely on the CSRF prevention
filter and do not contain internal mitigation for CSRF.
(CVE-2012-4431)

Warning: Before applying the update, back up your existing JBoss
Enterprise Web Server installation (including all applications and
configuration files).

Users of Tomcat should upgrade to these updated packages, which
resolve this issue. Tomcat must be restarted for this update to take
effect."
