<< Back VID 26837 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description Microsoft Security Update for December 2019 is not installed. - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2019-1484) - A denial of service vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the RDP service on the target system to stop responding. (CVE-2019-1453) - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-1474) - A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. 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. (CVE-2019-1468) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2019-1465, CVE-2019-1466, CVE-2019-1467) - An information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-1469) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle 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. (CVE-2019-1458) - An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. (CVE-2019-1470) - A security feature bypass vulnerability exists when Microsoft Defender improperly handles specific buffers. An attacker could exploit the vulnerability to trigger warnings and false positives when no threat is present. (CVE-2019-1488) - An elevation of privilege vulnerability exists when Windows improperly handles COM object creation. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges. (CVE-2019-1478) * 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://support.microsoft.com/en-us/help/4009469 https://support.microsoft.com/en-us/help/4009470 https://support.microsoft.com/en-us/help/4009471 https://support.microsoft.com/en-us/help/4000825 * Platforms Affected: 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 Windows Server 2016 Recommendation Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin December 2019 Microsoft security update at https://support.microsoft.com/en-us/help/4009469 https://support.microsoft.com/en-us/help/4009470 https://support.microsoft.com/en-us/help/4009471 https://support.microsoft.com/en-us/help/4000825 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com.
