## Overview

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt system processes and potentially execute arbitrary code with elevated privileges (SYSTEM privileges on Windows, and root privileges on macOS and Linux).

## Affected

- `globalprotect >= 6.0.0, < 6.0.15`
- `globalprotect >= 6.2.0, < 6.2.8`
- `globalprotect >= 6.2.0, <= 6.2.9`
- `globalprotect >= 6.3.0, < 6.3.3`
- `globalprotect >= 6.3.0, < 6.3.5`
- `globalprotect = 6.2.8`
- `globalprotect = 6.3.3`

## Remediation

Upgrade past the affected range:

- `globalprotect 6.3.5`
