Security Bulletin: IBM Rational ClearQuest CQOle ActiveX Control Remote Execution Vulnerability (CVE-2012-0708)

CVE ID: CVE-2012-0708

Description: A defect has been discovered where a ClearQuest Ole API function can be called with incorrect parameters causing a crash or possible execution of attack code. All versions of ClearQuest are affected. This affects only Windows platforms.

In order to be affected, the machine must have ClearQuest .dll files installed. These files are installed on a Microsoft Windows machine if any of the components of the ClearQuest installation are installed on a machine. This includes the following:

- ClearQuest Client (Eclipse-based)

- ClearQuest Client for Windows (Microsoft MFC-based)

- ClearQuest Web Server or server components

Machines which do not have any ClearQuest .dll files installed on them are not impacted. This includes using a browser to run the ClearQuest Web Client. The ClearQuest Web Server is the machine that has the .dll files installed on them. The machine running the browser which accesses the ClearQuest Web Server is not impacted, unless that browser's machine also has run a ClearQuest product installation and installed any ClearQuest components on that machine.
