{"id":"CVE-2021-4156","details":"An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws.","modified":"2026-03-15T22:42:50.475726Z","published":"2022-03-23T20:15:10.097Z","related":["ALSA-2022:1968","SUSE-SU-2022:0034-1","SUSE-SU-2022:0052-1","SUSE-SU-2022:0052-2","SUSE-SU-2022:14872-1","openSUSE-SU-2022:0052-1","openSUSE-SU-2024:11705-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/12/msg00013.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202309-11"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/06/msg00020.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/09/msg00036.html"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2027690"},{"type":"REPORT","url":"https://github.com/libsndfile/libsndfile/issues/731"},{"type":"FIX","url":"https://github.com/libsndfile/libsndfile/pull/732/commits/4c30646abf7834e406f7e2429c70bc254e18beab"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-4156.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"1.1.10"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"}]}
