    Debian Bug     : 873557
    
    An authentication bypass vulnerability was discovered in mbed TLS, a
    lightweight crypto and SSL/TLS library, when the authentication mode is
    configured as 'optional'. A remote attacker can take advantage of this
    flaw to mount a man-in-the-middle attack and impersonate an intended
    peer via an X.509 certificate chain with many intermediates.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 2.4.2-1+deb9u1.
    
    For the testing distribution (buster), this problem has been fixed
    in version 2.6.0-1.
    
    For the unstable distribution (sid), this problem has been fixed in
