Microsoft: >> Windows 10 >> 1903 Security Vulnerabilities
<p>A local elevation of privilege vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited the vulnerability could elevate privileges on an affected system from 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>

An information disclosure vulnerability exists when DirectWrite improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s 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 DirectWrite handles objects in memory.

An information disclosure vulnerability exists in the Windows kernel that could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (ASLR) bypass. An attacker who successfully exploited the vulnerability could retrieve the memory address of a kernel object.
To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.
The security update addresses the vulnerability by correcting how the Windows kernel handles memory addresses.
