{"id":"DEBIAN-CVE-2026-32836","details":"dr_libs dr_flac.h version 0.13.3 and earlier (fixed in commits fefced4, 4f5a4cd, and 663239a) contain an uncontrolled memory allocation vulnerability in drflac__read_and_decode_metadata() that allows attackers to trigger excessive memory allocation by supplying crafted PICTURE metadata blocks. Attackers can exploit attacker-controlled mimeLength and descriptionLength fields to cause denial of service through memory exhaustion when processing FLAC streams with metadata callbacks.","modified":"2026-09-14T17:03:30.127106385Z","published":"2026-03-17T20:16:14Z","upstream":["CVE-2026-32836"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-32836"}],"affected":[{"package":{"name":"libchdr","ecosystem":"Debian:13","purl":"pkg:deb/debian/libchdr?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20240929.aaca599+dfsg-1","0.0~git20250608.8bba774+dfsg-1","0.0~git20250608.8bba774+dfsg-2","0.0~git20250608.8bba774+dfsg-3","0.3.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32836.json"}},{"package":{"name":"libchdr","ecosystem":"Debian:14","purl":"pkg:deb/debian/libchdr?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20240929.aaca599+dfsg-1","0.0~git20250608.8bba774+dfsg-1","0.0~git20250608.8bba774+dfsg-2","0.0~git20250608.8bba774+dfsg-3","0.3.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32836.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/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"}]}
