The (1) ListView, (2) ListView2, (3) TreeView, and (4) TreeView2 ActiveX controls in MSCOMCTL.OCX in the Common Controls in Microsoft Office 2003 SP3, 2007 SP2 and SP3, and 2010 Gold and SP1; Office 2003 Web Components SP3; SQL Server 2000 SP4, 2005 SP4, and 2008 SP2, SP3, and R2; BizTalk Server 2002 SP1; Commerce Server 2002 SP4, 2007 SP2, and 2009 Gold and R2; Visual FoxPro 8.0 SP1 and 9.0 SP2; and Visual Basic 6.0 Runtime allow remote attackers to execute arbitrary code via a crafted (a) web site, (b) Office document, or (c) .rtf file that triggers "system state" corruption, as exploited in the wild in April 2012, aka "MSCOMCTL.OCX RCE Vulnerability."

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."

Heap-based buffer overflow in the Office Web Components ActiveX Control in Microsoft Office XP SP3, Office 2003 SP3, Office XP Web Components SP3, Office 2003 Web Components SP3, Office 2003 Web Components SP1 for the 2007 Microsoft Office System, Internet Security and Acceleration (ISA) Server 2004 SP3 and 2006 SP1, and Office Small Business Accounting 2006 allows remote attackers to execute arbitrary code via unspecified parameters to unknown methods, aka "Office Web Components Heap Corruption Vulnerability."

The "ConnectionFile" property in the DataSourceControl component in Office Web Components (OWC) 10 allows remote attackers to determine the existence of local files by detecting an exception.

The "XMLURL" property in the Spreadsheet component of Office Web Components (OWC) 10 follows redirections, which allows remote attackers to determine the existence of local files based on exceptions, or to read WorkSheet XML files.

The Load method in the Chart component of Office Web Components (OWC) 9 and 10 generates an exception when a specified file does not exist, which allows remote attackers to determine the existence of local files.

The Host function in Microsoft Office Web Components (OWC) 2000 and 2002 is exposed in components that are marked as safe for scripting, which allows remote attackers to execute arbitrary commands via the setTimeout method.

The LoadText method in the spreadsheet component in Microsoft Office Web Components (OWC) 2000 and 2002 allows remote attackers to read arbitrary files through Internet Explorer via a URL that redirects to the target file.

Microsoft Office Web Components (OWC) 2000 and 2002 allows remote attackers to bypass the "Allow paste operations via script" setting, even when it is disabled, via the (1) Copy method of the Cell object or (2) the Paste method of the Range object.
