{"id":"CVE-2018-12393","details":"A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.*. This vulnerability affects Firefox \u003c 63, Firefox ESR \u003c 60.3, and Thunderbird \u003c 60.3.","modified":"2026-04-16T06:15:39.498704578Z","published":"2019-02-28T18:29:00.663Z","related":["SUSE-SU-2018:3656-1","SUSE-SU-2018:3749-1","SUSE-SU-2018:3749-2","SUSE-SU-2018:3749-3","SUSE-SU-2018:3769-1","openSUSE-SU-2018:3687-1","openSUSE-SU-2024:10600-1","openSUSE-SU-2024:10601-1","openSUSE-SU-2024:14572-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/105718"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1041944"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2018/11/msg00011.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201811-13"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/105769"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3005"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3531"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3532"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201811-04"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4324"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3801-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3868-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4337"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2018-26/"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2018-27/"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2018-28/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3006"},{"type":"REPORT","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1495011"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"63.0"}]},{"events":[{"introduced":"0"},{"fixed":"60.3"}]},{"events":[{"introduced":"0"},{"fixed":"60.3"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.10"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"7.6"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-12393.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
