An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system. The update addresses the vulnerability by correcting the way in which the Windows Graphics Component handles objects in memory.
