Doc Text:	A flaw was found in FreeRDP, an open-source implementation of the Remote Desktop Protocol (RDP). This vulnerability, an integer overflow in the audio input redirection channel, allows a remote attacker to supply a malicious FramesPerPacket value. This can lead to a heap-based buffer overflow, potentially enabling arbitrary code execution on systems using the ALSA backend, or a denial of service across all supported platforms.

Description OSIDB Bzimport 2026-08-02 13:01:25 UTC

FreeRDP before 3.29.0 contains integer overflow vulnerabilities in the audio input redirection channel (audin) across ALSA, sndio, WinMM, and OpenSL ES backends that fail to validate the FramesPerPacket parameter from RDP servers. Attackers can supply a malicious FramesPerPacket value causing allocation size wraparound, resulting in heap-based buffer overflow on ALSA or denial of service on all platforms.
