Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4512482 or cumulative update 4512518. It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC). An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2019-1162)

- A security feature bypass vulnerability exists when Microsoft browsers improperly handle requests of different origins. The vulnerability allows Microsoft browsers to bypass Same-Origin Policy (SOP) restrictions, and to allow requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted.
(CVE-2019-1192)

- An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-1148, CVE-2019-1153)

- A denial of service vulnerability exists when the XmlLite runtime (XmlLite.dll) improperly parses XML input. An attacker who successfully exploited this vulnerability could cause a denial of service against an XML application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to an XML application. The update addresses the vulnerability by correcting how the XmlLite runtime parses XML input. (CVE-2019-1187)

- 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-2019-1146, CVE-2019-1147, CVE-2019-1155, CVE-2019-1156, CVE-2019-1157)

- <h1>Executive Summary</h1> Microsoft is aware of the Bluetooth BR/EDR (basic rate/enhanced data rate, known as &quot;Bluetooth Classic&quot;) key negotiation vulnerability that exists at the hardware specification level of any BR/EDR Bluetooth device. An attacker could potentially be able to negotiate the offered key length down to 1 byte of entropy, from a maximum of 16 bytes.
(CVE-2019-9506)

- An elevation of privilege vulnerability exists in the way that the wcmsvc.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2019-1180)

- An elevation of privilege exists in the p2pimsvc service where an attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges. (CVE-2019-1168)

- An information disclosure vulnerability exists when the Windows Graphics component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how the Windows Graphics Component handles objects in memory. (CVE-2019-1078)

- A memory corruption vulnerability exists in the Windows Server DHCP service when an attacker sends specially crafted packets to a DHCP failover server. An attacker who successfully exploited the vulnerability could cause the DHCP service to become nonresponsive.
(CVE-2019-1206)

- An elevation of privilege vulnerability exists in the way that the ssdpsrv.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2019-1178)

- A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the 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-2019-1144, CVE-2019-1145, CVE-2019-1149, CVE-2019-1150, CVE-2019-1151, CVE-2019-1152)

- An elevation of privilege vulnerability exists when the Windows kernel 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-2019-1159, CVE-2019-1164)

- A remote code execution vulnerability exists in Remote Desktop Services formerly known as Terminal Services when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests.
This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute 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. (CVE-2019-1181, CVE-2019-1182)

- A memory corruption vulnerability exists in the Windows DHCP client when an attacker sends specially crafted DHCP responses to a client. An attacker who successfully exploited the vulnerability could run arbitrary code on the client machine. (CVE-2019-0736)

- A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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-2019-1133, CVE-2019-1194)

- 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-2019-1183)

- An elevation of privilege vulnerability exists in the way that the rpcss.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2019-1177)

- A remote code execution vulnerability exists in the way that Microsoft browsers access objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to 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-2019-1193)

- A denial of service vulnerability exists when Microsoft Hyper-V Network Switch on a host server fails to properly validate input from a privileged user on a guest operating system. An attacker who successfully exploited the vulnerability could cause the host server to crash. (CVE-2019-0714, CVE-2019-0715, CVE-2019-0718, CVE-2019-0723)

- A denial of service vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited the vulnerability could cause a target system to stop responding. (CVE-2019-0716)

- 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 a 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 update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory.
(CVE-2019-1143, CVE-2019-1158)

- 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-2019-0720)

- A memory corruption vulnerability exists in the Windows Server DHCP service when processing specially crafted packets. An attacker who successfully exploited the vulnerability could cause the DHCP server service to stop responding. (CVE-2019-1212)
