Denial Of Service (DoS)

github.com/go-jose/go-jose is vulnerable to Billion Hashes Attack. The vulnerability is due to the decryptKey function in symmetric.go because it only checks if the value of p2c is a positive integer, but lacks a maximum size check. This allow an attacker to provide a PBES2 encrypted JWE blob wit...

GHSA-2C7C-3MJ9-8FQH Decryption of malicious PBES2 JWE objects can consume unbounded system resources

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...
