Synopsis

Important: tomcat6 security update

Type/Severity

Security Advisory: Important

Topic

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.

Description

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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
