XStream is a simple library to serialize objects to XML and back again. In
affected versions this vulnerability may allow a remote attacker has
sufficient rights to execute commands of the 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. XStream 1.4.18 uses no longer a
blacklist by default, since it cannot be secured for general purpose.
