"The version of IBM WebSphere MQ server is version 7.1 without Fix 
Pack 7.1.0.2 or 7.5 without Fix Pack 7.5.0.1. It is, therefore, 
affected by the following vulnerabilities :

  - A flaw exists in Global Security Kit (GSkit) due to a
    failure to properly validate data when the 'protection
    mechanism' is executed against an SSL CBC timing attack.
    A remote attacker, using crafted values in the TLS Record
    Layer, can exploit this to cause a denial of service.
    (CVE-2012-2191)

  - A flaw exists in Global Security Kit (GSkit) due to a
    failure to properly verify certificates, which can allow
    a remote attacker to conduct a man-in-the-middle attack.
    (CVE-2012-2203)

  - An application can potentially put a sequence of large
    messages into the queue, causing a buffer to overflow in
    the queue manager. This can lead to a denial of service.
    (CVE-2012-4863)");
