PHP JWT Library: PBES2-HS*+A*KW unwrap accepts an unbounded p2c iteration count, enabling CPU-amplification denial of service

Impact When a JWE uses a password-based key-encryption algorithm PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW, PBES2AESKW::unwrapKey reads the p2c PBKDF2 iteration count parameter directly from the attacker-controlled JOSE header and passes it to hashpbkdf2 with no upper bound. The...
