    Package        : pyjwt
    Debian Bug     : 781640
    
    Tim McLean discovered that pyjwt, a Python implementation of JSON Web
    Token, would try to verify an HMAC signature using an RSA or ECDSA public
    key as secret. This could allow remote attackers to trick applications
    expecting tokens signed with asymmetric keys, into accepting arbitrary
    tokens. For more information see:

    For the stable distribution (jessie), this problem has been fixed in
    version 0.2.1-1+deb8u1.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your pyjwt packages.
