{"id":"CVE-2023-22483","summary":"cmark-gfm Quadratic complexity bugs may lead to a denial of service","details":"cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. Versions prior to 0.29.0.gfm.7 are subject to several polynomial time complexity issues in cmark-gfm that may lead to unbounded resource exhaustion and subsequent denial of service. Various commands, when piped to cmark-gfm with large values, cause the running time to increase quadratically. These vulnerabilities have been patched in version 0.29.0.gfm.7.\n","aliases":["GHSA-29g3-96g3-jg6c"],"modified":"2026-03-14T12:02:00.879613Z","published":"2023-01-23T22:36:14.574Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/22xxx/CVE-2023-22483.json","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/22xxx/CVE-2023-22483.json"},{"type":"ADVISORY","url":"https://github.com/github/cmark-gfm/security/advisories/GHSA-29g3-96g3-jg6c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-22483"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/github/cmark-gfm","events":[{"introduced":"0"},{"fixed":"57d5e093ef801f54bf4174c900f7a863599bb47d"}]}],"versions":["0.27.1.gfm.2","0.27.1.gfm.3","0.27.1.gfm.4","0.28.0.gfm.10","0.28.0.gfm.11","0.28.0.gfm.5","0.28.0.gfm.6","0.28.0.gfm.7","0.28.0.gfm.8","0.28.0.gfm.9","0.28.3.gfm.12","0.28.3.gfm.13","0.28.3.gfm.14","0.28.3.gfm.15","0.28.3.gfm.16","0.28.3.gfm.17","0.28.3.gfm.18","0.28.3.gfm.19","0.28.3.gfm.20","0.29.0.gfm.0","0.29.0.gfm.1","0.29.0.gfm.2","0.29.0.gfm.3","0.29.0.gfm.4","0.29.0.gfm.5","0.29.0.gfm.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-22483.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
