Microsoft Internet Explorer 6.0.2900.2180, 7, and 8.0.7600.16385 executes a mail application in situations where an IFRAME element has a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many IFRAME elements.

Security readout for executives and security teams

This issue lets a malicious web page force affected Internet Explorer versions to repeatedly launch the user’s mail application. The impact described is denial of service and user disruption, not data theft or code execution. Business risk is mainly for legacy environments still using Internet Explorer to open untrusted HTML or web content. Exposure appears limited to systems using the listed legacy Internet Explorer versions with a registered mail application, especially when users browse untrusted pages or open untrusted HTML documents. The bundle’s affected-product metadata is incomplete, so validate against actual browser inventory. Treat this as a legacy-browser hygiene issue with user-disruption risk. Prioritize removal or containment where Internet Explorer remains in business workflows, but do not treat it as confirmed active exploitation based on the provided sources. Mitigation focus: Identify and retire the listed legacy Internet Explorer versions where possible.; Use supported browsers for internet and email-linked workflows.; Restrict affected Internet Explorer versions from opening untrusted HTML or web content..
