"Several security vulnerabilities were discovered in XStream, a Java
library to serialize objects to XML and back again.

CVE-2020-26258

XStream is vulnerable to a Server-Side Forgery Request which can be
activated when unmarshalling. The vulnerability may allow a remote
attacker to request data from internal resources that are not publicly
available only by manipulating the processed input stream.

CVE-2020-26259

Xstream is vulnerable to an Arbitrary File Deletion on the local host
when unmarshalling. The vulnerability may allow a remote attacker to
delete arbitrary known files on the host as long as the executing
process has sufficient rights only by manipulating the processed input
stream.

For Debian 9 stretch, these problems have been fixed in version
1.4.11.1-1+deb9u1.

We recommend that you upgrade your libxstream-java packages.
