CVE-2007-2216: Microsoft Internet Explorer

High severity, CVSS 9.3. EPSS: 41.4% chance of exploitation in the next 30 days.

The tblinf32.dll (aka vstlbinf.dll) ActiveX control for Internet Explorer 5.01, 6 SP1, and 7 uses an incorrect IObjectsafety implementation, which allows remote attackers to execute arbitrary code by requesting the HelpString property, involving a crafted DLL file argument to the TypeLibInfoFromFile function, which overwrites the HelpStringDll property to call the DLLGetDocumentation function in another DLL file, aka "ActiveX Object Vulnerability."

Affected products

• Microsoft Internet Explorer: version 5.01 only; version 6 only; version 7 only
