Microsoft Windows Graphics Component Multiple Vulnerabilities

Information disclosure vulnerabilities exist when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerabilities could obtain information to further compromise the user’s system.

There are multiple ways an attacker could exploit the vulnerabilities, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The update addresses the vulnerabilities by correcting how the Windows GDI component handle objects in memory.
