CVE-2022-46449Public exploitNetwork attack vector

Unauthenticated service crash via error-length misuse

Published Jan 10, 2023 · Updated Apr 9, 2025

An out-of-bounds write in Music Player Daemon 0.23.10 on Windows allows remote attackers to crash the service with a crafted command. Error formatting in src/system/Error.hxx trusts snprintf's would-have-written length after truncation, then writes a separator beyond a fixed stack buffer. An unauthenticated network client can trigger the fault with an oversized listplaylist argument that enters the error-logging path, terminating MPD.
