Target Milestone: ---
Classification: Other
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.
