"Updated tomcat6 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
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.

Apache Tomcat is a servlet container.

It was found that when an application used FORM authentication, along
with another component that calls request.setUserPrincipal() before
the call to FormAuthenticator#authenticate() (such as the
Single-Sign-On valve), it was possible to bypass the security
constraint checks in the FORM authenticator by appending
'/j_security_check' to the end of a URL. A remote attacker with an
authenticated session on an affected application could use this flaw
to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
(CVE-2012-3546)

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."
