Advisories for Maven/Org.bitbucket.b_c/Jose4j package

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.

The jose4j component before 0.9.4 for Java allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.

jose4j before v0.9.3 allows attackers to set a low iteration count of 1000 or less.

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.
