The most severe vulnerability could allow remote code execution if a user views shared content that embeds TrueType font files. An attacker who successfully exploited this vulnerability could take complete control of an affected system. This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the subsection, Affected and Non-Affected Software, in this section. The security update addresses these vulnerabilities by correcting the way Windows handles specially crafted TrueType Font (TTF) files and by correcting the way that Windows handles objects in memory. Affected Software Windows XP Service Pack 3 (2850851) Windows XP Professional x64 Edition Service Pack 2 (2850851) Windows Server 2003 Service Pack 2 (2850851) Windows Server 2003 x64 Edition Service Pack 2 (2850851) Windows Server 2003 with SP2 for Itanium-based Systems (2850851) Windows Vista Service Pack 2 (2850851) Windows Vista x64 Edition Service Pack 2 (2850851) Windows Server 2008 for 32-bit Systems Service Pack 2 (2850851) Windows Server 2008 for x64-based Systems Service Pack 2 (2850851) Windows Server 2008 for Itanium-based Systems Service Pack 2 (2850851) Windows 7 for 32-bit Systems Service Pack 1 (2850851) Windows 7 for x64-based Systems Service Pack 1 (2850851) Windows Server 2008 R2 for x64-based Systems Service Pack 1 (2850851) Windows Server 2008 R2 for Itanium-based Systems Service Pack 1 (2850851) Windows 8 for 32-bit Systems (2850851) Windows 8 for 64-bit Systems (2850851) Windows Server 2012 (2850851) Windows RT[1] (2850851) Windows Server 2008 for 32-bit Systems Service Pack 2 (Server Core installation) (2850851) Windows Server 2008 for x64-based Systems Service Pack 2 (Server Core installation) (2850851) Windows Server 2008 R2 for x64-based Systems Service Pack 1 (Server Core installation) (2850851) Windows Server 2012 (Server Core installation) (2850851) Vulnerability Information Win32k Memory Allocation Vulnerability- CVE-2013-1300 An elevation of privilege vulnerability exists when the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code with elevated privileges. Win32k Dereference Vulnerability - CVE-2013-1340 An elevation of privilege vulnerability exists in the way that the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code with elevated privileges. Win32k Vulnerability - CVE-2013-1345 An elevation of privilege vulnerability exists in the way that the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code with elevated privileges. TrueType Font Parsing Vulnerability - CVE-2013-3129 A remote code execution vulnerability exists in the way that affected components handle specially crafted TrueType font files. The vulnerability could allow remote code execution if a user opens a specially crafted TrueType font file. 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 with full administrative rights. Win32k Information Disclosure Vulnerability- CVE-2013-3167 An information disclosure vulnerability that could lead to elevation of privilege exists in the way that the Windows kernel-mode driver improperly handles objects in memory. Win32k Buffer Overflow Vulnerability - CVE-2013-3172 A denial of service vulnerability exists in the way that the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could cause the target system to stop responding. Win32k Buffer Overwrite Vulnerability - CVE-2013-3173 An elevation of privilege vulnerability exists in the way that the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code with elevated privileges. Win32k Read AV Vulnerability - CVE-2013-3660 A theoretical remote code execution vulnerability exists when the Windows kernel-mode driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability as a remote code execution vulnerability could execute arbitrary code in the security context of the Windows kernel. However, since the remote attack vector is not likely, it is more likely that an attacker would first need to log on to the target system to successfully exploit this vulnerability and gain elevated privileges. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
