The most severe of these vulnerabilities could allow remote code execution if an attacker sends a specially crafted response to a Windows print spooler request. This security update is rated Critical for all supported editions of Windows XP and Windows Server 2003; Important for all supported editions of Windows Vista; and Moderate for all supported editions of Windows Server 2008, Windows 7, and Windows 2008 R2. For more information, see the subsection, Affected and Non- 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 Windows Server 2008 for 32-bit Systems Service Pack 2 (Server Core installation) Windows Server 2008 for x64-based Systems Service Pack 2 (Server Core installation) Windows Server 2008 R2 for x64-based Systems (Server Core installation) Windows Server 2008 R2 for x64-based Systems Service Pack 1 (Server Core installation) Vulnerability Information Remote Administration Protocol Denial of Service Vulnerability - CVE-2012-1850 A denial of service vulnerability exists in Windows networking components. The vulnerability is due to the service not properly handling specially crafted RAP requests. Anattacker who successfully exploited this vulnerability could cause a target application to stop responding. Print Spooler Service Format String Vulnerability - CVE-2012-1851 A remote code execution vulnerability exists in the Windows Print Spooler service that could allow a remote, unauthenticated attacker to execute arbitrary code on an affected system. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts. Remote Administration Protocol Heap Overflow Vulnerability - CVE-2012-1852 A remote code execution vulnerability exists in the way that Windows networking components handle a specially crafted RAP response. An attacker who successfully exploited this vulnerability could run arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Remote Administration Protocol Stack Overflow Vulnerability - CVE-2012-1853 A remote code execution vulnerability exists in the way that Windows networking components handle specially crafted RAP responses. An attacker who successfully exploited this vulnerability could run arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
