{"id":"DEBIAN-CVE-2026-82522","details":"libjxl before 0.12 contains an integer underflow vulnerability in the container box parser that allows remote attackers to inject arbitrary metadata by exploiting 64-bit box size truncation to size_t on 32-bit platforms. Attackers can supply a crafted JPEG XL file causing the decoder to parse attacker-controlled codestream bytes as phantom box headers, enabling injection of arbitrary metadata (Exif, XMP, IPTC, JUMBF) and potential out-of-bounds reads.","modified":"2026-09-24T08:47:39.374493136Z","published":"2026-09-02T18:21:27.587Z","upstream":["CVE-2026-82522"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-82522"}],"affected":[{"package":{"name":"jpeg-xl","ecosystem":"Debian:12","purl":"pkg:deb/debian/jpeg-xl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.3-1","0.10.3-2","0.10.3-3","0.10.3-4","0.10.3-5","0.10.4-1","0.10.4-2","0.11.1-1","0.11.1-2","0.11.1-3","0.11.1-4","0.11.1-5","0.11.1-6","0.11.2-0.1","0.11.2-0.1~deb13u1","0.11.2-0.1~deb13u2","0.11.2-1","0.11.2-2","0.11.2-3","0.11.2-3~exp1","0.11.2-4","0.11.2-5","0.11.2-5.1","0.7.0-10","0.7.0-10+deb12u1","0.7.0-10.1","0.7.0-10.2","0.8.0-1","0.8.0~git20221120.4167056-1","0.8.0~git20221123.8bf8deb-1","0.8.0~git20230102.26a5158-1","0.8.0~git20230118.bcacd51-1","0.8.0~git20230125.a67e970-1","0.8.1-1","0.8.1-2","0.8.2-1","0.8.2-2","0.8.2-3","0.8.2-4","0.9.0~git20230612.38b629f-1","0.9.0~git20230612.38b629f-2","0.9.0~git20230612.38b629f-3","0.9.0~git20230612.38b629f-4","0.9.0~git20230623.689da0f-1","0.9.0~git20230623.689da0f-2","0.9.0~git20230623.689da0f-3","0.9.0~git20230623.689da0f-4","0.9.2-1","0.9.2-10","0.9.2-2","0.9.2-3","0.9.2-4","0.9.2-5","0.9.2-6","0.9.2-7","0.9.2-8","0.9.2-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82522.json"}},{"package":{"name":"jpeg-xl","ecosystem":"Debian:13","purl":"pkg:deb/debian/jpeg-xl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.11.1-4","0.11.1-5","0.11.1-6","0.11.2-0.1","0.11.2-0.1~deb13u1","0.11.2-0.1~deb13u2","0.11.2-1","0.11.2-2","0.11.2-3","0.11.2-3~exp1","0.11.2-4","0.11.2-5","0.11.2-5.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82522.json"}},{"package":{"name":"jpeg-xl","ecosystem":"Debian:14","purl":"pkg:deb/debian/jpeg-xl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.11.1-4","0.11.1-5","0.11.1-6","0.11.2-0.1","0.11.2-0.1~deb13u1","0.11.2-0.1~deb13u2","0.11.2-1","0.11.2-2","0.11.2-3","0.11.2-3~exp1","0.11.2-4","0.11.2-5","0.11.2-5.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82522.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/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"}]}
