Topic
An update for JBoss Enterprise Application Platform 6.0.1 which fixes
multiple security issues is now available from the Red Hat Customer Portal.

which give detailed severity ratings, are available for each vulnerability

Description
JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise
Application Platform. It provides a single deployment platform for the
JavaServer Pages (JSP) and Java Servlet technologies.
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 in JBoss Web. 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)
Multiple weaknesses were found in the JBoss Web DIGEST authentication
implementation, effectively reducing the security normally provided by
DIGEST authentication. A remote attacker could use these flaws to perform
replay attacks in some circumstances. (CVE-2012-5885, CVE-2012-5886,
CVE-2012-5887)
Warning: Before applying this update, back up your existing JBoss
