"It was found that XStream is vulnerable to Remote Code Execution. The
vulnerability may allow a remote attacker to run arbitrary shell
commands only by manipulating the processed input stream. Users who
rely on blocklists are affected (the default in Debian). We strongly
recommend to use the whitelist approach of XStream's Security
Framework because there are likely more class combinations the
blacklist approach may not address.

For Debian 9 stretch, this problem has been fixed in version
1.4.9-2+deb9u1.

We recommend that you upgrade your libxstream-java packages.
