Vulnerability Details : CVE-2011-5046 (1 public exploit)

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 Security Bulletin MS12-008 MS12-008 - Critical : Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Remote Code Execution (2660465) - Version: 1.0 Severity Rating: Critical Revision Note: V1.0 (February 14, 2012): Bulletin published. Summary: This security update resolves a privately reported vulnerability and a publicly disclosed vulnerability in Microsoft Windows. The more severe of these vulnerabilities could allow remote code execution if a user visits a website containing specially crafted content or if a specially crafted application is run locally. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.Release Date:2012-02-14
