| summary: Decryption of malicious PBES2 JWE objects can consume unbounded system resources |
| description: |- |
| 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. |
