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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L","score":3.8},"cwes":["CWE-835"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00034.html","http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00038.html","https://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=de594e47659029316bbf9391efb79da0a1a08e08","https://lists.debian.org/debian-lts-announce/2019/09/msg00021.html","https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html"],"products":["canonical:ubuntu_linux","opensuse:leap","qemu:qemu"],"source":"nvd","synced_at":"2026-10-19T20:59:10.855360465+00:00"},"epss":{"cve":"CVE-2019-12068","score":0.0051,"percentile":0.43532,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
