Share Email Share Email Subscribe ▲ Systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability. The updates address the vulnerability by correcting how Internet Explorer validates code integrity. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine.

This is a strong move in the right direction, as trimming the code base leads to shrinking the attack surface. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
