- CWE-193
Description
Music Player Daemon (MPD) before version 0.24.11 contains a stack buffer overflow vulnerability in the pcm_unpack_24be function in src/pcm/Pack.cxx that allows unauthenticated attackers to corrupt stack memory by triggering an off-by-one write in the PCM decoder plugin. Attackers can issue two MPD commands referencing a malicious HTTP audio source to cause the unpack loop to write 1366 entries into a 1365-entry buffer, overwriting four bytes past the array boundary with three attacker-controlled bytes from an HTTP response body, resulting in daemon termination or potential code execution.
