{"id":"GO-2023-1602","summary":"Denial of service via deflate decompression bomb in github.com/russellhaering/gosaml2","details":"A bug in SAML authentication library can result in Denial of Service attacks.\n\nAttackers can craft a \"deflate\"-compressed request which will consume significantly more memory during processing than the size of the original request. This may eventually lead to memory exhaustion and the process being killed.","aliases":["CVE-2023-26483","GHSA-6gc3-crp7-25w5"],"modified":"2026-03-17T04:30:40.191506Z","published":"2023-03-03T17:17:54Z","database_specific":{"url":"https://pkg.go.dev/vuln/GO-2023-1602","review_status":"REVIEWED"},"references":[{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-6gc3-crp7-25w5"},{"type":"FIX","url":"https://github.com/russellhaering/gosaml2/commit/f9d66040241093e8702649baff50cc70d2c683c0"},{"type":"WEB","url":"https://github.com/russellhaering/gosaml2/releases/tag/v0.9.0"}],"affected":[{"package":{"name":"github.com/russellhaering/gosaml2","ecosystem":"Go","purl":"pkg:golang/github.com/russellhaering/gosaml2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.9.0"}]}],"ecosystem_specific":{"imports":[{"path":"github.com/russellhaering/gosaml2","symbols":["DecodeUnverifiedBaseResponse","DecodeUnverifiedLogoutResponse","SAMLServiceProvider.RetrieveAssertionInfo","SAMLServiceProvider.ValidateEncodedLogoutRequestPOST","SAMLServiceProvider.ValidateEncodedLogoutResponsePOST","SAMLServiceProvider.ValidateEncodedResponse","SAMLServiceProvider.validationContext","maybeDeflate","parseResponse"]}]},"database_specific":{"source":"https://vuln.go.dev/ID/GO-2023-1602.json"}}],"schema_version":"1.7.5"}
