Updated rh-java-common-apache-commons-collections packages which fix one security issue are now available for Red Hat Software Collections 2

Solution

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

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

The 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 rh-java-common-apache-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.
