"The version of IBM MQ Server running on the remote host is affected by a vulnerability as referenced in the 7271937
advisory.

  - 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.
    (CVE-2024-29371)
