"Updated jakarta-commons-collections packages that fix one security
issue are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security 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.

The Jakarta/Apache Commons Collections library provides new
interfaces, implementations, and utilities to extend the features of
the Java Collections Framework.

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)

With this update, deserialization of certain classes in the
commons-collections library is no longer allowed. Applications that
require those classes to be deserialized can use the system property
'org.apache.commons.collections.enableUnsafeSerialization' to
re-enable their deserialization.

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

All users of jakarta-commons-collections are advised to upgrade to
these updated packages, which contain a backported patch to correct
this issue. All running applications using the commons-collections
library must be restarted for the update to take effect."
