    descriptionThe remote Windows host is missing security update 4516033 or cumulative update 4516065. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists when Windows Hyper-V Network Switch on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2019-0719) - An elevation of privilege vulnerability exists in Windows Text Service Framework (TSF) when the TSF server process does not validate the source of input or commands it receives. An attacker who successfully exploited this vulnerability could inject commands or read input sent through a malicious Input Method Editor (IME). This only affects systems that have installed an IME. (CVE-2019-1235) - An information disclosure exists in the Windows Common Log File System (CLFS) driver when it fails to properly handle sandbox checks. An attacker who successfully exploited this vulnerability could potentially read data outside their expected limits. (CVE-2019-1282) - An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-1274) - An information disclosure vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could obtain information that could be useful for further exploitation. (CVE-2019-1283) - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2019-1240, CVE-2019-1241, CVE-2019-1242, CVE-2019-1243, CVE-2019-1246, CVE-2019-1247, CVE-2019-1248, CVE-2019-1249, CVE-2019-1250) - An elevation of privilege vulnerability exists in Microsoft Compatibility Appraiser where a configuration file, with local privileges, is vulnerable to symbolic link and hard link attacks. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. (CVE-2019-1267) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user.

    descriptionThe remote Windows host is missing security update 4516051 or cumulative update 4516026. It is, therefore, affected by multiple vulnerabilities : - 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-2019-1252, CVE-2019-1286) - An elevation of privilege vulnerability exists in Windows Text Service Framework (TSF) when the TSF server process does not validate the source of input or commands it receives. An attacker who successfully exploited this vulnerability could inject commands or read input sent through a malicious Input Method Editor (IME). This only affects systems that have installed an IME. (CVE-2019-1235) - An information disclosure exists in the Windows Common Log File System (CLFS) driver when it fails to properly handle sandbox checks. An attacker who successfully exploited this vulnerability could potentially read data outside their expected limits. (CVE-2019-1282) - A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2019-1280) - An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-1274) - An elevation of privilege exists in hdAudio.sys which may lead to an out of band write. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. (CVE-2019-1271) - A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2019-1240, CVE-2019-1241, CVE-2019-1242, CVE-2019-1243, CVE-2019-1246, CVE-2019-1247, CVE-2019-1248, CVE-2019-1249, CVE-2019-1250) - An elevation of privilege exists when Winlogon does not properly handle file path information. An attacker who successfully exploited this vulnerability could run arbitrary code. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-1268) - A security feature bypass vulnerability exists when Microsoft Browsers fail to validate the correct Security Zone of requests for specific URLs. This could allow an attacker to cause a user to access a URL in a less restricted Internet Security Zone than intended. (CVE-2019-1220) - A remote code execution vulnerability exists in the Windows Remote Desktop Client when a user connects to a malicious server. An attacker who successfully exploited this vulnerability could execute arbitrary code on the computer of the connecting client. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-1291) - 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-2019-1256, CVE-2019-1285) - An elevation of privilege vulnerability exists when DirectX improperly 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. (CVE-2019-1284) - A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-1208, CVE-2019-1236) - An information disclosure vulnerability exists when the Windows Transaction Manager improperly handles objects in memory. An attacker who successfully exploited this vulnerability could potentially read data that was not intended to be disclosed. (CVE-2019-1219) - An elevation of privilege vulnerability exists in the way that ws2ifsl.sys (Winsock) handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated privileges. (CVE-2019-1215) - An information disclosure vulnerability exists when DirectWrite 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 DirectWrite handles objects in memory. (CVE-2019-1244, CVE-2019-1245) - An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2019-1214)
