## Overview

An integer overflow in the remote-control
screen processing component of TeamViewer clients (Full Client, Portable and Remote
Control App) prior to version 15.83 may allow a malicious remote host to cause
a denial of service or, depending on the platform, potentially execute
arbitrary code with the privileges of the viewer process. Exploitation requires
a user to establish a remote-control session to an attacker-controlled or
compromised host.

## Affected

- `full_client < 15.83`
- `full_client >= 15.64.0 (Legacy Windows 7 & 8) < 15.64.10 (Legacy Windows 7 & 8)`
- `full_client >= 14.7.0 (Windows) < 14.7.48868 (Windows)`
- `full_client >= 14.7.0 (Linux) < 14.7.48868 (Linux)`
- `full_client >= 14.7.0 (macOS) < 14.7.48868 (macOS)`
- `full_client >= 13.2.0 (Windows) < 13.2.36231 (Windows)`
- `full_client >= 13.2.0 (Linux) < 13.2.154008 (Linux)`
- `full_client >= 13.2.0 (macOS) < 13.2.154007 (macOS)`
- `Portable < 15.83`
- `Portable >= 15.64.0 (Legacy Windows 7 & 8) < 15.64.10 (Legacy Windows 7 & 8)`
- `remote_control < 15.83`
