Name of the Vulnerable Software and Affected Versions jose4j versions prior to 0.9.4 Description The issue is related to the improper implementation of the PBES2 algorithm in the jose4j component when handling the p2c parameter. This can allow a remote attacker to cause a denial of service due to...

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...

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...

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...

GO-2023-2334 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...

JOSE vulnerable to resource exhaustion via specifically crafted JWE

The PBKDF2-based JWE key management algorithms expect a JOSE Header Parameter named p2c PBES2 Count, which determines how many PBKDF2 iterations must be executed in order to derive a CEK wrapping key. The purpose of this parameter is to intentionally slow down the key derivation function in order...

CVE-2022-36083 JOSE vulnerable to resource exhaustion via specifically crafted JWE

JOSE is "JSON Web Almost Everything" - JWA, JWS, JWE, JWT, JWK, JWKS with no dependencies using runtime's native crypto in Node.js, Browser, Cloudflare Workers, Electron, and Deno. The PBKDF2-based JWE key management algorithms expect a JOSE Header Parameter named p2c PBES2 Count, which determine...
