## Overview

FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the client video redirection channel that allows malicious servers to crash clients by sending out-of-order messages. Attackers can send a Geometry CLEAR message that nulls presentation->geometry, then send VideoData that dereferences it, causing client denial of service.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
