{"id":"AZL-32251","summary":"CVE-2023-50269 affecting package squid 5.7-5","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":"2026-04-01T05:10:59.831060Z","published":"2023-12-14T18:15:45Z","upstream":["CVE-2023-50269"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-50269"}],"affected":[{"package":{"name":"squid","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/squid"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.7-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-32251.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
