The TabStrip ActiveX control in the Common Controls library (MSCOMCTL.OCX) shipped with Microsoft Office, along with several other Microsoft products including SQL Server, Commerce Server, Host Integration Server, Visual FoxPro and the Visual Basic 6.0 Runtime, contains a flaw in which system-state corruption can be triggered. An attacker who supplies a crafted document or web page can use this to execute arbitrary code, and the attack requires no privileges but does require a user to open the document or visit the page.
The TabStrip ActiveX control in the Common Controls in MSCOMCTL.OCX in Microsoft Office 2003 SP3, Office 2003 Web Components SP3, Office 2007 SP2 and SP3, Office 2010 SP1, SQL Server 2000 SP4, SQL Server 2005 SP4, SQL Server 2008 SP2, SP3, R2, R2 SP1, and R2 SP2, Commerce Server 2002 SP4, Commerce Server 2007 SP2, Commerce Server 2009 Gold and R2, Host Integration Server 2004 SP1, Visual FoxPro 8.0 SP1, Visual FoxPro 9.0 SP2, and Visual Basic 6.0 Runtime allows remote attackers to execute arbitrary code via a crafted (1) document or (2) web page that triggers system-state corruption, aka "MSCOMCTL.OCX RCE Vulnerability."
