{"id":"GHSA-v464-r2r9-www7","summary":"Ollama Vulnerable to Denial of Service (DoS) via Crafted GZIP","details":"An Out-Of-Memory (OOM) vulnerability exists in the `ollama` server version 0.3.14. This vulnerability can be triggered when a malicious API server responds with a gzip bomb HTTP response, leading to the `ollama` server crashing. The vulnerability is present in the `makeRequestWithRetry` and `getAuthorizationToken` functions, which use `io.ReadAll` to read the response body. This can result in excessive memory usage and a Denial of Service (DoS) condition.","aliases":["CVE-2024-12886","GO-2025-3548"],"modified":"2025-03-31T17:44:33.215400Z","published":"2025-03-20T12:32:44Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2025-03-21T17:25:07Z","nvd_published_at":"2025-03-20T10:15:31Z","cwe_ids":["CWE-400","CWE-409"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-12886"},{"type":"PACKAGE","url":"https://github.com/ollama/ollama"},{"type":"WEB","url":"https://huntr.com/bounties/f115fe52-58af-4844-ad29-b1c25f7245df"}],"affected":[{"package":{"name":"github.com/ollama/ollama","ecosystem":"Go","purl":"pkg:golang/github.com/ollama/ollama"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.3.14"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-v464-r2r9-www7/GHSA-v464-r2r9-www7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
