{"id":"CVE-2023-28119","summary":"crewjam/saml vulnerable to Denial Of Service Via Deflate Decompression Bomb","details":"The crewjam/saml go library contains a partial implementation of the SAML standard in golang. Prior to version 0.4.13, the package's use of `flate.NewReader` does not limit the size of the input. The user can pass more than 1 MB of data in the HTTP request to the processing functions, which will be decompressed server-side using the Deflate algorithm. Therefore, after repeating the same request multiple times, it is possible to achieve a reliable crash since the operating system kills the process. This issue is patched in version 0.4.13.\n","aliases":["GHSA-5mqj-xc49-246p","GO-2023-1664"],"modified":"2026-08-12T03:51:35.596941515Z","published":"2023-03-22T19:51:13.210Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28119.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28119.json"},{"type":"ADVISORY","url":"https://github.com/crewjam/saml/security/advisories/GHSA-5mqj-xc49-246p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28119"},{"type":"FIX","url":"https://github.com/crewjam/saml/commit/8e9236867d176ad6338c870a84e2039aef8a5021"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/crewjam/saml","events":[{"introduced":"5049389b651c221c331aba4b07060159c11c401a"},{"fixed":"8e9236867d176ad6338c870a84e2039aef8a5021"}],"database_specific":{"extracted_events":[{"introduced":"0.4.12"},{"last_affected":"0.4.12"}],"source":["CPE_STRING","REFERENCES"],"cpe":"cpe:2.3:a:saml_project:saml:0.4.12:*:*:*:*:go:*:*"}}],"versions":["0.4.12","v0.4.12"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-28119.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
