Jwcrypto: jwcrypto: denial of service via malformed jwe tokens
A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a Memory…

Jwcrypto: jwcrypto: denial of service via o(n^2) duplicate check on unbounded jwk key_ops array
A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK wit…
