Out-of-Bounds Access in FreeRDP Audio Format Parsing

Publication date: 2026-02-09

Last updated on: 2026-02-10

Assigner: GitHub, Inc.

Description

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, audin_server_recv_formats frees an incorrect number of audio formats on parse failure (i + i), leading to out-of-bounds access in audio_formats_free. This vulnerability is fixed in 3.22.0.

Attack-Flow Graph

Executive Summary

This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, the function audin_server_recv_formats incorrectly frees an incorrect number of audio formats when a parsing failure occurs. Specifically, it frees (i + i) audio formats instead of the correct amount, which leads to an out-of-bounds memory access in the audio_formats_free function.

This issue is fixed in FreeRDP version 3.22.0.

Impact Analysis

The out-of-bounds access caused by this vulnerability can lead to memory corruption, which may result in application crashes or potentially allow an attacker to execute arbitrary code or cause a denial of service. Since the vulnerability is exploitable remotely without authentication, it poses a high risk to affected systems.
