{"id":"DEBIAN-CVE-2026-49127","details":"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.","modified":"2026-09-14T17:03:43.396648518Z","published":"2026-05-28T20:16:26.387Z","upstream":["CVE-2026-49127"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-49127"}],"affected":[{"package":{"name":"mpd","ecosystem":"Debian:12","purl":"pkg:deb/debian/mpd?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.23.12-1","0.23.14-1","0.23.14-2","0.23.15-1","0.23.15-1~bpo12+1","0.23.16-1","0.23.17-1","0.24-1","0.24.1-1","0.24.12-1","0.24.2-1","0.24.2-1~bpo12+1","0.24.3-1","0.24.4-1","0.24.6-1","0.24.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49127.json"}},{"package":{"name":"mpd","ecosystem":"Debian:13","purl":"pkg:deb/debian/mpd?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.24.12-1","0.24.4-1","0.24.6-1","0.24.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49127.json"}},{"package":{"name":"mpd","ecosystem":"Debian:14","purl":"pkg:deb/debian/mpd?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.24.12-1"}]}],"versions":["0.24.4-1","0.24.6-1","0.24.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49127.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
