"Updated packages that fix one security issue for the Apache
commons-collections library for Red Hat JBoss Enterprise Application
Platform 6.3 are now available for Red Hat Enterprise Linux 5, 6, and
7.

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 6 is a platform for Java
applications based on JBoss Application Server 7.

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 6.3 on Red
Hat Enterprise Linux 6 are advised to upgrade to these updated
packages. The JBoss server process must be restarted for the update to
take effect."
