Executive Summary

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

There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how DirectWrite handles objects in memory.
