Description

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.

In the interim, the quickest way to resolve this specific deserialization vulnerability is to remove the vulnerable class files (InvokerTransformer, InstantiateFactory, and InstantiateTransformer) in all commons-collections jar files. Any manual changes should be tested to avoid unforseen complications.

All running applications using the commons-collections library must be restarted for the update to take effect.
