Denial of service via decryption of malicious PBES2 JWE objects in github.com/go-jose/go-jose/v3

The go-jose package is subject to a “billion hashes attack” causing denial-of-service when decrypting JWE inputs. This occurs when an attacker can provide a PBES2 encrypted JWE blob with a very large p2c value that, when decrypted, produces a denial-of-service.
