Vulnerability Description

Vulnerability Details
The vulnerability is due to the way Internet Explorer handles the loading of IESHIMS.DLL. A remote attacker can exploit this vulnerability by enticing a target user to save a maliciously crafted dynamic link library (DLL) file on the desktop or modify the system variable PATH.
