    It was discovered that python-ecdsa, a cryptographic signature library for Python, did not correctly verify DER encoded signatures. Malformed signatures could lead to unexpected exceptions and in some cases did not raise any exception.
    
    Package        : python-ecdsa
    Version        : 0.11-1+deb8u1
    CVE ID         : CVE-2019-14853 CVE-2019-14859
    
    It was discovered that python-ecdsa, a cryptographic signature library
    for Python, did not correctly verify DER encoded signatures. Malformed
    signatures could lead to unexpected exceptions and in some cases did
    not raise any exception.
    
    For Debian 8 "Jessie", these problems have been fixed in version
    0.11-1+deb8u1.
    
    We recommend that you upgrade your python-ecdsa packages.
