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


From Red Hat Security Advisory 2015:2521 :

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:

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.
