This could allow remote attackers to trick applications expecting tokens signed with asymmetric keys, into accepting arbitrary tokens. For more information see: https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/ 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.
