pyjwt vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04 - Ubuntu 16.04 LTS
Summary:
PyJWT could be made to crash if it received specially crafted input.
Software Description: - pyjwt: Python implementation of JSON Web Token
Details:
It was discovered that a vulnerability in PyJWT doesn't check invalid_strings properly for some public keys. A remote attacker could take advantage of a key confusion to craft JWTs from scratch.

The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.04:  python-jwt                      1.4.2-1ubuntu0.1  python3-jwt                     1.4.2-1ubuntu0.1
Ubuntu 16.04 LTS:  python-jwt                      1.3.0-1ubuntu0.1  python3-jwt                     1.3.0-1ubuntu0.1
