USN-5526-2: PyJWT regression
17 August 2022
USN-5526-1 introduced a regression in PyJWT.
- pyjwt - Python 3 implementation of JSON Web Token
USN-5526-1 fixed vulnerabilities in PyJWT. Unfortunately this caused a
regression by incrementing the internal package version number on Ubuntu
22.04 LTS. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Aapo Oksman discovered that PyJWT incorrectly handled signatures
constructed from SSH public keys. A remote attacker could use this to forge
a JWT signature.
