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 occupy a thread that consumes maximum CPU time and will
never return. 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.
