Scientific Linux Security Update : apache-commons-collections on SL7.x (noarch)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

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.
