https://notcve.org/view.php?id=CVE-2021-28652
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege. Se detectó un problema en Squid versiones anteriores a 4.15 y versiones 5.x anteriores a 5.0.6. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 https://bugs.squid-cache.org/show_bug.cgi?id=5106 https://github.com/squid-cache/squid/security/advisories/GHSA-m47m-9hvw-7447 https://lists.debian.org/debian-lts-announce/2021/06/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LSQ3U54ZCNXR44QRPW3AV2VCS6K3TKCF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraprojec • CWE-401: Missing Release of Memory after Effective Lifetime •

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request processing. Se detectó un problema en Squid versiones anteriores a 4.15 y versiones 5.x anteriores a 5.0.6. Debido a un bug de administración de la memoria, es vulnerable a un ataque de Denegación de Servicio (contra todos los clientes que usan el proxy) por medio del procesamiento de peticiones HTTP Range An incorrect input validation flaw was found in Squid, where it is vulnerable to a denial of service attack against all clients using the proxy. The highest threat from this vulnerability is to system availability. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 http://www.squid-cache.org/Versions/v4/changesets/squid-4-e7cf864f938f24eea8af0692c04d16790983c823.patch https://github.com/squid-cache/squid/security/advisories/GHSA-pxwq-f3qr-w2xf https://lists.debian.org/debian-lts-announce/2021/06/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LSQ3U54ZCNXR44QRPW3AV2VCS6K3TKCF https://lists.fedoraproject.org/archive • CWE-20: Improper Input Validation CWE-116: Improper Encoding or Escaping of Output •

https://notcve.org/view.php?id=CVE-2021-31807
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. An integer overflow problem allows a remote server to achieve Denial of Service when delivering responses to HTTP Range requests. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent. Se ha detectado un problema en Squid versiones anteriores a 4.15 y en versiones 5.x anteriores a 5.0.6. Un problema de desbordamiento de enteros permite a un servidor remoto conseguir una Denegación de Servicio cuando se entrega respuestas a peticiones de rango HTTP. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 http://www.squid-cache.org/Versions/v4/changesets/squid-4-e7cf864f938f24eea8af0692c04d16790983c823.patch https://github.com/squid-cache/squid/security/advisories/GHSA-pxwq-f3qr-w2xf https://lists.debian.org/debian-lts-announce/2021/06/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LSQ3U54ZCNXR44QRPW3AV2VCS6K3TKCF https://lists.fedoraproject.org/archive • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
