Scientific Linux Security Update : apache-commons-collections on SL7.x (noarch) (20151130)

critical Nessus Plugin ID 87120

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.

Solution

Update the affected packages.
