Additional Information

Microsoft Internet Explorer is a Web browser available for Microsoft Windows.

Internet Explorer is prone to a remote code-execution vulnerability due to a use-after-free condition. Specifically, this issue exists because Internet Explorer accesses an object in memory that was already freed.

Attackers can exploit this issue by enticing an unsuspecting user to view a specially crafted webpage.

Attackers can exploit this issue to execute arbitrary code in the context of the currently logged-in user. Failed attacks will cause denial-of-service conditions.
