{"id":"CVE-2026-32836","details":"dr_libs dr_flac.h version 0.13.3 and earlier 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":"2026-04-02T13:26:13.465992Z","published":"2026-03-17T20:16:14Z","references":[{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mackron-dr-libs-excessive-memory-allocation-in-picture-metadata-parsing"},{"type":"REPORT","url":"https://github.com/mackron/dr_libs/issues/298"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mackron/dr_libs","events":[{"introduced":"0"},{"last_affected":"69d777c482775858e8ea8a7b047c9bcd451febc8"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"0.13.3"}]}}],"versions":["flac-0.12.43","flac-0.13.0","flac-0.13.1","flac-0.13.2","flac-0.13.3","mp3-0.6.40","mp3-0.7.0","mp3-0.7.1","mp3-0.7.2","wav-0.13.17","wav-0.14.0","wav-0.14.1","wav-0.14.2","wav-0.14.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32836.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
