An issue was discovered in dvsekhvalnov jose2go 1.5.0 thru 1.7.0 allowing an attacker to cause a Denial-of-Service (DoS) via crafted JSON Web Encryption (JWE) token with an exceptionally high compression ratio.
The jose2go component before 1.6.0 for Go allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.
An attacker controlled input of a PBES2 encrypted JWE blob can have a very large p2c value that, when decrypted, produces a denial-of-service.
