<< Back VID 26791 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description The Hotfix (MS16-106, 3185848) for 'Security Update for Microsoft Graphics Component' has not been applied. This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Multiple Win32k Elevation of Privilege Vulnerabilities Multiple elevation of privilege vulnerabilities exist in the way that certain Windows kernel-mode drivers handle objects in memory. An attacker who successfully exploited these vulnerabilities could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. GDI Information Disclosure Vulnerability ? CVE-2016-3354 An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. An attacker who successfully exploited this vulnerability could use the retrieved information to circumvent Address Space Layout Randomization (ASLR) in Windows, which helps guard against a broad class of vulnerabilities. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability, such as a remote code execution vulnerability, that is capable of leveraging the ASLR circumvention. GDI Elevation of Privilege Vulnerability ? CVE-2016-3355 An elevation of privilege vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory. 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 user rights. GDI Remote Code Execution Vulnerability ? CVE-2016-3356 A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. * Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts. * References: https://technet.microsoft.com/en-us/library/security/ms16-106 * Platforms Affected: Windows Vista SP2 Windows Vista x64 SP2 Windows Server 2008 SP2 Windows Server 2008 x64 SP2 Windows 7 SP1 Windows 7 x64 SP1 Windows Server 2008 R2 SP1 Windows Server 2008 R2 x64 SP1 Windows 8.1 Windows Server 2012 Windows Server 2012 R2 Windows 10 Recommendation Apply the appropriate patch(3185848) for your system, as listed in Microsoft Security Bulletin MS16-106 at https://technet.microsoft.com/en-us/library/security/ms16-106 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com.
