Multiple local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app allows a local user to escalate their privileges to NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux. This enables a non-administrative user to execute arbitrary commands with administrative privileges. This GlobalProtect app on iOS, Android and ChromeOS is not impacted.
