NVD Description

Note: Versions mentioned in the description apply only to the upstream xstream package and not the xstream package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
