CVE-2011-1205: Multiple buffer overflows in unspecified COM objects in Rational Common Licensing 7.0 through 7.1.1.4 in IB...

Security readout for executives and security teams

CVE-2011-1205 is a legacy IBM Rational licensing issue where malformed local HTML could trigger buffer overflows in COM objects and let a local user gain higher privileges. The main concern is old ClearCase, ClearQuest, or Rational Common Licensing installations still present on developer or build workstations. Exposure is most likely on legacy Windows systems running IBM Rational ClearCase, ClearQuest, or Rational Common Licensing 7.x components. The source bundle does not identify all affected “other products,” so asset discovery should include broader Rational tooling of that era. Handle as a legacy software exposure review, not an emergency internet-facing incident based on available evidence. Prioritize if Rational 7.x tooling remains on sensitive engineering systems where local privilege escalation could compromise source code, build processes, or release integrity. Mitigation focus: Identify hosts running affected IBM Rational 7.x licensing components.; Review IBM advisory swg21470998 for vendor-supported fixes or upgrade paths.; Remove unsupported Rational components from workstations and build hosts..
