https://notcve.org/view.php?id=CVE-2021-31808
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this. 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 comprobación de entrada, es vulnerable a ataques de Denegación de Servicio (contra todos los clientes que usan el proxy). • 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 •

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 •

https://notcve.org/view.php?id=CVE-2021-28651
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.
