    It was discovered that jackson-databind, a Java library used to parse
    JSON and other data formats, did not properly validate user input
    before attempting deserialization. This allowed an attacker providing
    maliciously crafted input to perform code execution, or read arbitrary
    files on the server.
    
    For the oldstable distribution (stretch), these problems have been fixed
    in version 2.8.6-1+deb9u6.
    
    For the stable distribution (buster), these problems have been fixed in
    version 2.9.8-3+deb10u1.
    
    We recommend that you upgrade your jackson-databind packages.
    
    For the detailed security status of jackson-databind please refer to
    its security tracker page at:
