{"id":"CVE-2019-12068","details":"In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's-\u003edsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.","modified":"2026-03-12T22:58:20.476059Z","published":"2019-09-24T20:15:11.747Z","related":["SUSE-SU-2019:14199-1","SUSE-SU-2019:14201-1","SUSE-SU-2019:2753-1","SUSE-SU-2019:2769-1","SUSE-SU-2019:2783-1","SUSE-SU-2019:2954-1","SUSE-SU-2019:2955-1","SUSE-SU-2019:2956-1","SUSE-SU-2020:0388-1","SUSE-SU-2020:14396-1","SUSE-SU-2020:1514-1","SUSE-SU-2020:1526-1","SUSE-SU-2020:1538-1","SUSE-SU-2021:14706-1","openSUSE-SU-2019:2505-1","openSUSE-SU-2019:2510-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html"},{"type":"WEB","url":"https://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=de594e47659029316bbf9391efb79da0a1a08e08"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/09/msg00021.html"},{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2019-12068"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4191-2/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00034.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00038.html"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4191-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4665"},{"type":"FIX","url":"https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg01518.html"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"1:4.1-1"}]},{"events":[{"introduced":"0"},{"last_affected":"1:2.1+dfsg-12+deb8u6"}]},{"events":[{"introduced":"0"},{"last_affected":"1:2.8+dfsg-6+deb9u8"}]},{"events":[{"introduced":"0"},{"last_affected":"1:3.1+dfsg-8+deb10u2"}]},{"events":[{"introduced":"0"},{"last_affected":"1:3.1+dfsg-8~deb10u1"}]},{"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":"19.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.10"}]},{"events":[{"introduced":"0"},{"last_affected":"15.0"}]},{"events":[{"introduced":"0"},{"last_affected":"15.1"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-12068.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L"}]}
