{"id":"DEBIAN-CVE-2026-88362","details":"MuJS e892c9fdb contains an incorrect numeric conversion vulnerability in jsR_isindex() in jsrun.c. A specially crafted JavaScript input containing an excessively large numeric array index can cause an out-of-range floating-point value to be converted to an integer without proper range validation. This results in undefined behavior and can cause process termination, leading to denial of service.","modified":"2026-09-26T09:00:12.612760103Z","published":"2026-09-24T16:17:13.350Z","upstream":["CVE-2026-88362"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88362"}],"affected":[{"package":{"name":"mujs","ecosystem":"Debian:12","purl":"pkg:deb/debian/mujs?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.10-1","1.3.2-1","1.3.3-1","1.3.3-2","1.3.3-3","1.3.5-1","1.3.6-1","1.3.7-1","1.3.8-1","1.3.8-2","1.3.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88362.json"}},{"package":{"name":"mujs","ecosystem":"Debian:13","purl":"pkg:deb/debian/mujs?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.10-1","1.3.6-1","1.3.7-1","1.3.8-1","1.3.8-2","1.3.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88362.json"}},{"package":{"name":"mujs","ecosystem":"Debian:14","purl":"pkg:deb/debian/mujs?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.10-1","1.3.6-1","1.3.7-1","1.3.8-1","1.3.8-2","1.3.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88362.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
