"Updated packages for the Apache commons-collections library for Red
Hat JBoss Enterprise Application Platform 5.2, which fix one security
issue, are now available for Red Hat Enterprise Linux 4, 5, and 6.

Red Hat Product Security has rated this update as having Critical
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.

Red Hat JBoss Enterprise Application Platform 5 is a platform for Java
applications based on JBoss Application Server 6.

It was found that the Apache commons-collections library permitted
code execution when deserializing objects involving a specially
constructed chain of classes. A remote attacker could use this flaw to
execute arbitrary code with the permissions of the application using
the commons-collections library. (CVE-2015-7501)

Further information about this security flaw may be found at:
https://access.redhat.com/solutions/2045023

All users of Red Hat JBoss Enterprise Application Platform 5.2 on Red
Hat Enterprise Linux 4, 5, and 6 are advised to upgrade to these
updated packages. The JBoss server process must be restarted for the
update to take effect."
