Astra Linux – Vulnerability in python-jwcrypto

JWCrypto implements the JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker could cause a denial-of-service attack by passing in a malicious JWE Token with a high compression ratio. When the server processed this token, it would consume a lot of memory...

Important: python-jwcrypto

Issue Overview: A flaw was found in jwcrypto. The JWK.importkey function validates the keyops JWK member for duplicate values using an algorithm with On^2 time complexity, and the length of keyops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large keyops array to an...
