    Package : libxstream-java
    CVE ID : CVE-2020-26217

    It was discovered that the default blacklist of XStream, a Java library
    to serialise objects to XML and back again, was vulnerable to the
    execution of arbitrary shell commands by manipulating the processed
    input stream.

    For additional defense-in-depth it is recommended to switch to the
    whitelist approach of XStream's security framework. For additional
    information please refer to https://github.com/x-stream/xstream/security/advisories/GHSA-mw36-7c6c-q4q2

    For the stable distribution (buster), this problem has been fixed in
    version 1.4.11.1-1+deb10u1.

    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: https://security-tracker.debian.org/tracker/libxstream-java
