TITLE

Microsoft Windows 7 Professional 64-bit Service disruption in (DoS) Vulnerabilities

DESCRIPTION

The Graphics Device Interface (GDI) in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly validate user-mode input, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted data, as demonstrated by a large height attribute of an IFRAME element rendered by Safari, aka "GDI Access Violation Vulnerability.". Microsoft Windows 7 Professional 64-bit of kernel-mode Driver win32k.sys Is Apple Safari Service disruption when using ( Memory corruption ) A vulnerability exists that could lead to state and arbitrary code execution.By a third party IFRAME Excessively large height Service operation disruption via attributes ( Memory corruption ) Could be put into a state and execute arbitrary code.
