{"id":"ALPINE-CVE-2023-50269","details":"Squid is a caching proxy for the Web. 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.","modified":"2026-09-15T08:17:48.419254868Z","published":"2023-12-14T18:15:45.070Z","upstream":["CVE-2023-50269"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-50269"}],"affected":[{"package":{"name":"squid","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-50269.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"}]}
