## Summary

TeamViewer Full Client for Linux and macOS is affected by this flaw in its screen-image decoder, which can let a remote attacker run arbitrary code on the computer through crafted screen data during a remote-control session or a malicious session recording file. Exploitation requires a user to take some action, such as opening the specially crafted file.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- TeamViewer Full Client: fixed in 15.83; from 14.7.0 (Linux), fixed in 14.7.48868 (Linux); from 14.7.0 (macOS), fixed in 14.7.48868 (macOS); from 13.2.0 (Linux), fixed in 13.2.154008 (Linux); from 13.2.0 (macOS), fixed in 13.2.154007 (macOS)

## Description

An out-of-bounds write vulnerability in the screen-image decoder of TeamViewer Full Client for Linux and macOS prior to version 15.83 allows a remote attacker to execute arbitrary code by supplying crafted screen-image data during a remote-control session. The vulnerability can also be exploited by persuading a user to open a specially crafted TeamViewer session recording (.tvs). Missing destination bounds checking in the decoder allows crafted screen-image data to cause an out-of-bounds write to the image buffer. Exploitation requires user interaction.

## What to do

- Check your stack: if you ship or depend on TeamViewer Full Client, upgrade to a fixed version (15.83, 14.7.48868 (Linux), 14.7.48868 (macOS), 13.2.154008 (Linux), 13.2.154007 (macOS)) per the references below.
