CVSS: 6.5EPSS: 17%CPEs: 5EXPL: 0CVE-2021-28662 – squid: denial of service in HTTP response processing
https://notcve.org/view.php?id=CVE-2021-28662
An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic. Se detectó un problema en Squid versiones 4.x anteriores a 4.15 y versiones 5.x anteriores a 5.0.6. Si un servidor remoto envía un determinado encabezado de respuesta por medio de HTTP o HTTPS, ocurre una denegación de servicio. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 http://www.squid-cache.org/Versions/v6/changesets/squid-6-051824924c709bd6162a378f746fb859454c674e.patch https://github.com/squid-cache/squid/commit/051824924c709bd6162a378f746fb859454c674e https://github.com/squid-cache/squid/security/advisories/GHSA-jjq6-mh2h-g39h https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LSQ3U54ZCNXR44QRPW3AV2VCS6K3TKCF https://lists.fedoraproject.org/a • CWE-20: Improper Input Validation CWE-116: Improper Encoding or Escaping of Output •

https://notcve.org/view.php?id=CVE-2021-31806
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 •

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 •

An issue was discovered in Squid through 4.13 and 5.x through 5.0.4. Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings. Se detectó un problema en Squid versiones hasta 4.13 y versiones 5.x hasta 5.0.4. Debido a una comprobación inapropiada de la entrada, permite a un cliente confiable llevar a cabo un Trafico No Autorizado de Peticiones HTTP y acceder a servicios que de otro modo estarían prohibidos por los controles de seguridad. • http://www.squid-cache.org/Versions/v4/changesets/SQUID-2020_11.patch http://www.squid-cache.org/Versions/v5/changesets/SQUID-2020_11.patch https://github.com/squid-cache/squid/security/advisories/GHSA-jvf6-h9gj-pmj6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJMDRVV677AJL4BZAOLCT5LMFCGBZTC2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FBXFWKIGXPERDVQXG556LLPUOCMQGERC https://lists.fedoraproject.org/archives/list/package-announc • CWE-20: Improper Input Validation CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
