CVE ID         : CVE-2020-26258 CVE-2020-26259

Liaogui Zhong discovered two security issues in XStream, a Java library
to serialise objects to XML and back again, which could result in the
deletion of files or server-side request forgery when unmarshalling.

For the stable distribution (buster), these problems have been fixed in
