    It was discovered that python-ecdsa, a cryptographic signature library
    for Python, incorrectly handled certain signatures. A remote attacker
    could use this issue to cause python-ecdsa to either not warn about
    incorrect signatures, or generate exceptions resulting in a
    denial-of-service.
    
    For the oldstable distribution (stretch), these problems have been fixed
    in version 0.13-2+deb9u1.
    
    For the stable distribution (buster), these problems have been fixed in
    version 0.13-3+deb10u1.
    
    We recommend that you upgrade your python-ecdsa packages.
