Analysis
The TabStrip ActiveX control in MSCOMCTL.OCX across Microsoft Office, SQL Server, and Commerce Server allows remote code execution through crafted documents, serving as a secondary exploit vector alongside CVE-2012-0158.
Technical Context
Similar to CVE-2012-0158, the TabStrip control fails to properly validate data when loading ActiveX content from documents. The memory corruption allows attackers to achieve code execution when the victim opens a crafted document.
