Due to an Uncontrolled Recursion bug in versions 2.6 through 2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives."}],"source":{"advisory":"GHSA-wgq4-4cfg-c4x3","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T22:16:46.315Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/squid-cache/squid/security/advisories/GHSA-wgq4-4cfg-c4x3","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/squid-cache/squid/security/advisories/GHSA-wgq4-4cfg-c4x3"},{"name":"http://www.squid-cache.org/Versions/v5/SQUID-2023_10.patch","tags":["x_refsource_MISC","x_transferred"],"url":"http://www.squid-cache.org/Versions/v5/SQUID-2023_10.patch"},{"name":"http://www.squid-cache.org/Versions/v6/SQUID-2023_10.patch","tags":["x_refsource_MISC","x_transferred"],"url":"http://www.squid-cache.org/Versions/v6/SQUID-2023_10.patch"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MEV66D3PAAY6K7TWDT3WZBLCPLASFJDC/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A5QASTMCUSUEW3UOMKHZJB3FTONWSRXS/","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/01/msg00003.html","tags":["x_transferred"]},{"url":"https://security.netapp.com/advisory/ntap-20240119-0005/","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2023-12-19T14:21:27.775746Z","id":"CVE-2023-50269","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-05-21T14:31:00.896Z"}}]}}
