Windows Server 2019

<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>Show less

<p>A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system.</p> <p>To exploit the vulnerability, a user would have to open a specially crafted file.</p> <p>The security update addresses the vulnerability by correcting how Microsoft Graphics Components handle objects in memory.</p>Show less

<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>Show less

<p>An elevation of privilege vulnerability exists when the Windows iSCSI Target Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.</p> <p>To exploit the vulnerability, an attacker would first need code execution on a victim system. An attacker could then run a specially crafted application.</p> <p>The security update addresses the vulnerability by ensuring the Windows iSCSI Target Service properly handles file operations.</p>Show less

<p>An elevation of privilege vulnerability exists when the Windows Backup Service improperly handles file operations.</p> <p>To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges.</p> <p>The security update addresses the vulnerability by correcting how the Windows Backup Service handles file operations.</p>Show less
