This signature detects attempts to exploit a remote memory corruption vulnerability in Microsoft Internet Explorer.
Microsoft Internet Explorer is prone to a remote memory-corruption vulnerability. Specifically, this issue occurs because the browser fails to properly handle objects in memory. This may allow attackers to embed an ActiveX control marked 'safe for initialization' in an application or Microsoft Office document that hosts the browser rendering engine.
Attackers can exploit this issue by enticing an unsuspecting user to view a specially crafted web page.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the affected application.
