{"id":"JLSEC-2026-571","details":"libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 800-byte HEIF sequence file causes an infinite loop in Box_stts::get_sample_duration(), consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and is triggered during file open (parsing) - before any user interaction or image decoding. The process stays alive (no crash, no error logged), making it invisible to crash-based monitoring. This issue has been fixed in version 1.22.0.","modified":"2026-06-05T15:30:16.721486811Z","published":"2026-06-05T15:18:28.412Z","upstream":["CVE-2026-32739","EUVD-2026-30975"],"database_specific":{"sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32739","published":"2026-05-19T20:16:18.780Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-32739","modified":"2026-05-20T14:17:13.740Z","id":"CVE-2026-32739","database_specific":{"status":"Analyzed"},"imported":"2026-06-05T14:52:24.521Z"},{"html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-30975","published":"2026-05-19T19:10:03Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-30975","modified":"2026-05-20T13:07:09Z","id":"EUVD-2026-30975","imported":"2026-06-05T14:52:25.868Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/strukturag/libheif/releases/tag/v1.22.0"},{"type":"WEB","url":"https://github.com/strukturag/libheif/security/advisories/GHSA-j9g7-q9hv-gq8c"}],"affected":[{"package":{"name":"libheif_jll","ecosystem":"Julia","purl":"pkg:julia/libheif_jll?uuid=a13778fd-9a17-58b4-b5a0-4b4a242815a9"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.22.2000+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-571.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
