Note: the XStream project recommends to setup its security framework with a whitelist limited to the minimal required types, rather than relying on the black list (which got updated to address this vulnerability). The project is also phasing out maintenance of the black list, see [link moved to references] . For Debian 9 stretch, this problem has been fixed in version 1.4.11.1-1+deb9u3. We recommend that you upgrade your libxstream-java packages. For the detailed security status of libxstream-java please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
