Microsoft: >> Windows Server 2016 >> 1903 Security Vulnerabilities
<p>An elevation of privilege vulnerability exists when Windows Hyper-V on a host server fails to properly handle objects in memory. An attacker who successfully exploited these vulnerabilities could gain elevated privileges on a target operating system.</p>
<p>This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.</p>
<p>The update addresses the vulnerabilities by correcting how Windows Hyper-V handles objects in memory.</p>

<p>A denial of service vulnerability exists when Microsoft Hyper-V on a host server fails to properly validate specific malicious data from a user on a guest operating system.</p>
<p>To exploit the vulnerability, an attacker who already has a privileged account on a guest operating system, running as a virtual machine, could run a specially crafted application.</p>
<p>The security update addresses the vulnerability by resolving the conditions where Hyper-V would fail to handle these requests.</p>

<p>A denial of service vulnerability exists in Microsoft Outlook software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could cause a remote denial of service against a system.</p>
<p>Exploitation of the vulnerability requires that a specially crafted email be sent to a vulnerable Outlook server.</p>
<p>The security update addresses the vulnerability by correcting how Microsoft Outlook handles objects in memory.</p>

<p>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.</p>
<p>To exploit this vulnerability, an attacker would need to run a specially crafted application against a server which provides Remote Desktop Protocol (RDP) services.</p>
<p>The update addresses the vulnerability by correcting how RDP handles connection requests.</p>

<p>A security feature bypass vulnerability exists in Microsoft Word software when it fails to properly handle .LNK files. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user.</p>
<p>To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Word software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.</p>
<p>The security update addresses the vulnerability by correcting how Microsoft Word handles these files.</p>

<p>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.</p>
<p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.</p>
<p>The update addresses the vulnerability by correcting how the Windows COM Server creates COM objects.</p>
