"The version of IBM WebSphere MQ server is version 7.0 without Fix
Pack 7.0.1.9, 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)");
