The remote Windows host is missing security update 4499165 or cumulative update 4499151. It is, therefore, affected by multiple vulnerabilities :
A new subclass of speculative execution side channel vulnerabilities, known as Microarchitectural Data Sampling, exist in Windows.
An attacker who successfully exploited these vulnerabilities may be able to read privileged data across trust boundaries. In shared resource environments (such as exists in some cloud services configurations), these vulnerabilities could allow one virtual machine to improperly access information from another. In non-browsing scenarios on standalone systems, an attacker would need prior access to the system or an ability to run a specially crafted application on the target system to leverage these vulnerabilities.
(CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091)
A denial of service vulnerability exists when .NET Framework and .NET Core improperly process RegEx strings. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Framework (or .NET core) application. The update addresses the vulnerability by correcting how .NET Framework and .NET Core applications handle RegEx string processing. (CVE-2019-0820)
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-2019-0940)
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-2019-0885)
An elevation of privilege vulnerability exists when the Windows Kernel improperly handles key enumeration. An attacker who successfully exploited the vulnerability could gain elevated privileges on a targeted system. A locally authenticated attacker could exploit this vulnerability by running a specially crafted application. The security update addresses the vulnerability by helping to ensure that the Windows Kernel properly handles key enumeration. (CVE-2019-0881)
An elevation of privilege vulnerability exists in Microsoft Windows when Windows fails to properly handle certain symbolic links. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions. (CVE-2019-0936)
An spoofing vulnerability exists when Internet Explorer improperly handles URLs. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2019-0921)
An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. (CVE-2019-0707)
A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. 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-2019-0884, CVE-2019-0911, CVE-2019-0918)
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-2019-0889, CVE-2019-0890, CVE-2019-0891, CVE-2019-0893, CVE-2019-0894, CVE-2019-0895, CVE-2019-0896, CVE-2019-0897, CVE-2019-0898, CVE-2019-0899, CVE-2019-0900, CVE-2019-0901, CVE-2019-0902)
A memory corruption vulnerability exists in the Windows Server DHCP service when processing specially crafted packets. An attacker who successfully exploited the vulnerability could run arbitrary code on the DHCP server. (CVE-2019-0725)
A denial of service vulnerability exists when .NET Framework improperly handles objects in heap memory. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. (CVE-2019-0864)
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-2019-0758, CVE-2019-0882, CVE-2019-0961)
An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.
An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-0930)
An elevation of privilege vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully decode and replace authentication request using Kerberos, allowing an attacker to be validated as an Administrator. The update addresses this vulnerability by changing how these requests are validated. (CVE-2019-0734)
An elevation of privilege vulnerability exists in the way Windows Error Reporting (WER) handles files. 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 administrator privileges. (CVE-2019-0863)
A denial of service vulnerability exists when .NET Framework or .NET Core improperly handle web requests.
An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Framework or .NET Core web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework or .NET Core application.
The update addresses the vulnerability by correcting how .NET Framework or .NET Core web applications handles web requests. (CVE-2019-0980, CVE-2019-0981)
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. (CVE-2019-0903)
