Duo Authentication Proxy Installer Denial of Service Vulnerability

The Duo Authentication Proxy installer prior to 5.2.1 did not properly validate file installation paths. This allows an attacker with local user privileges to coerce the installer to write to arbitrary privileged directories. If successful, an attacker can manipulate files used by Duo Authentication Proxy installer, cause Denial of Service (DoS) by deleting file(s), or replace system files to potentially achieve elevation of privileges. This is only exploitable during new installations, while the installer is running, and is not exploitable once installation has finished. Versions 5.2.1 of Duo Authentication Proxy installer addresses this issue.

NVIDIA GeForce Experience, all versions prior to 3.22, contains a vulnerability in GameStream plugins where log files are created using NT/System level permissions, which may lead to code execution, denial of service, or local privilege escalation. The attacker does not have control over the consequence of a modification nor would they be able to leak information as a direct result of the overwrite.
