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 •
CVSS: 6.8EPSS: 0%CPEs: 6EXPL: 1CVE-2021-28652 – squid: denial of service issue in Cache Manager
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 •

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 •
CVSS: 6.5EPSS: 3%CPEs: 28EXPL: 0CVE-2021-31807 – squid: incorrect memory management in HTTP Range header
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. 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=5104 https://github.com/squid-cache/squid/security/advisories/GHSA-ch36-9jhx-phm4 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-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
