Microsoft: >> Windows Server 2016 >> 1903 Security Vulnerabilities
An elevation of privilege vulnerability exists when reparse points are created by sandboxed processes allowing sandbox escape. An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system.
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.
The security update addresses the vulnerability by preventing sandboxed processes from creating reparse points targeting inaccessible files.

An information disclosure vulnerability exists in SymCrypt during the OAEP decryption stage. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.
The update addresses the vulnerability through a software change to the OAEP decoding operations.

An elevation of privilege vulnerability exists when DirectX improperly handles objects in memory. 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 full user rights.
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.
The update addresses the vulnerability by correcting how DirectX handles objects in memory.
