jose4j is vulnerable to DoS via compressed JWE content

In jose4j before 0.9.6, an attacker can cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression.

Chosen Ciphertext Attack in Jose4j

### Summary RSA1_5 in jose4j is susceptible to chosen ciphertext attacks. The attack allows to decrypt RSA1_5 or RSA_OAEP encrypted ciphertexts. It may be feasible to sign with affected keys. ### Severity Moderate - exploiting this ciphertext attack could result in the ability to decrypt RSA1_5 or RSA_OAEP encrypted ciphertexts. ### Proof of Concept A test case that can reproduce the padding oracle uses the following private key: ``` { "kty": "RSA", "alg": "RSA1_5", "u
