Microsoft: >> Windows 10 >> 1903 Security Vulnerabilities
<p>An elevation of privilege vulnerability exists when the Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p>
<p>In a local attack scenario, an attacker could exploit this vulnerability by running a specially crafted application to take control over the affected system.</p>
<p>The update addresses the vulnerability by correcting the way in which the Microsoft Graphics Component handles objects in memory and preventing unintended elevation from user mode.</p>

<p>An elevation of privilege vulnerability exists when Active Directory Federation Services (ADFS) improperly handles multi-factor authentication requests. An attacker who successfully exploited this vulnerability could bypass some, but not all, of the authentication factors.</p>
<p>To exploit this vulnerability, an attacker could send a specially crafted authentication request.</p>
<p>This security update corrects how ADFS handles multi-factor authentication requests.</p>

<p>An elevation of privilege vulnerability exists when NTFS improperly checks access. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p>
<p>To exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.</p>
<p>The security update addresses the vulnerability by correcting how NTFS checks access.</p>

<p>An elevation of privilege vulnerability exists in the way that the dnsrslvr.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.</p>
<p>To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the dnsrslvr.dll properly handles objects in memory.</p>

<p>An elevation of privilege vulnerability exists when the Shell infrastructure component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</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 the way in which the Shell infrastructure component handles objects in memory and preventing unintended elevation from lower integrity application.</p>

<p>An information disclosure vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system (low-integrity to medium-integrity).</p>
<p>This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted.</p>
<p>The security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls.</p>

<p>An elevation of privilege vulnerability exists when the Windows Storage Services improperly handle 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 Storage Services properly handle file operations.</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 remote code execution vulnerability exists when the Windows Text Service Module improperly handles memory. An attacker who successfully exploited the vulnerability could gain execution on a victim system.</p>
<p>An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge (Chromium-based), and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by way of enticement in an email or Instant Messenger message, or by getting them to open an attachment sent through email.</p>
<p>The security update addresses the vulnerability by correcting how the Windows Text Service Module handles memory.</p>
