An attacker can use two HTTP requests to upload a malformed GGUF file containing just 4 bytes starting with the GGUF custom magic header. By leveraging a custom Modelfile that includes a FROM statement pointing to the attacker-controlled blob file, the attacker can crash the application through the CreateModel route, leading to a segmentation fault (signal SIGSEGV: segmentation violation).","published":"2024-10-31T00:00:00Z","modified":"2026-08-07T11:50:00.268949188Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/ollama/ollama","fixedVersion":"0.1.46"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/ollama/ollama/compare/v0.1.45...v0.1.46#diff-782c2737eecfa83b7cb46a77c8bdaf40023e7067baccd4f806ac5517b4563131L417"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39720.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39720"},{"type":"ARTICLE","url":"https://oligo.security/blog/more-models-more-probllms"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:00.268949188Z"}}
