An information disclosure vulnerability exists when Microsoft Word improperly discloses the contents of its memory.

To exploit the vulnerability, an attacker could craft a special document file and then convince the user to open it. An attacker must know the memory address location where the object was created. The update addresses the vulnerability by changing the way certain Word functions handle objects in memory.
