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.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
