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. This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the subsection, Affected Software, in this section. Affected Software Windows XP Service Pack 3 Windows XP Professional x64 Edition Service Pack 2 Windows Server 2003 Service Pack 2 Windows Server 2003 x64 Edition Service Pack 2 Windows Server 2003 with SP2 for Itanium-based Systems Windows Vista Service Pack 2 Windows Vista x64 Edition Service Pack 2 Windows Server 2008 for 32-bit Systems Service Pack 2**** Windows Server 2008 for x64-based Systems Service Pack 2**** Windows Server 2008 for Itanium-based Systems Service Pack 2 Windows 7 for 32-bit Systems Windows 7 for 32-bit Systems Service Pack 1 Windows 7 for x64-based Systems Windows 7 for x64-based Systems Service Pack 1 Windows Server 2008 R2 for x64-based Systems Windows Server 2008 R2 for x64-based Systems Service Pack 1**** Windows Server 2008 R2 for Itanium-based Systems Windows Server 2008 R2 for Itanium-based Systems Service Pack 1 ****Server Core installation affected. This update applies, with a lower severity rating, to supported editions of Windows Server 2008 or Windows Server 2008 R2 as indicated, when installed using the Server Core installation option. For more information on this installation option, see the TechNet articles, Managing a Server Core Installation and Servicing a Server Core Installation. Note that the Server Core installation option does not apply to certain editions of Windows Server 2008 and Windows Server 2008 R2; see Compare Server Core Installation Options. Vulnerability Information GDI Access Violation Vulnerability - CVE-2011-5046 A remote code execution vulnerability exists in the Windows kernel due to improper validation of input passed from user mode through the kernel component of GDI. The vulnerability could allow an attacker to run code in kernel-mode and then install programs; view, change, or delete data; or create new accounts with full administrative rights. Keyboard Layout Use After Free Vulnerability - CVE-2012-0154 An elevation of privilege vulnerability exists due to the way that the Windows kernel-mode driver manages specific keyboard layouts. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
