CVE-2013-3918Windows information card control — out-of-bounds write

An ActiveX control shipped with a decade of Windows releases writes outside its bounds when a crafted page drives it, letting that page run code as the person browsing. It appeared in a watering-hole campaign in 2013.

YOUR NEXT MOVE

Retire these Windows versions — most are far out of support; where one must stay, apply the 2013 update and set the kill bit for the control.
