"Updated tomcat6 packages that fix one security issue are now available
for Red Hat Enterprise Linux 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 for the Java Servlet and
JavaServer Pages (JSP) technologies.

A session fixation flaw was found in the Tomcat FormAuthenticator
module. During a narrow window of time, if a remote attacker sent
requests while a user was logging in, it could possibly result in the
attacker's requests being processed as if they were sent by the user.
(CVE-2013-2067)

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