FreeRDP before 3.29.0 contains an out-of-bounds heap read vulnerability in the UVC H.264 extension-unit parser that fails to validate descriptor length before accessing the GUID field. A local attacker with a malicious USB video camera can trigger a heap read beyond allocated bounds during camera stream setup, causing denial of service.

A flaw was found in FreeRDP. This out-of-bounds read vulnerability in the Universal Video Class (UVC) H.264 extension-unit parser occurs because the software fails to validate descriptor length before accessing the GUID field. A local attacker, by connecting a specially crafted malicious USB video camera, can trigger a read beyond the allocated memory bounds during camera stream setup. This can lead to a denial of service (DoS), making the application unavailable.
