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.

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.

CVSS: 9.6EPSS: 0%CPEs: 12EXPL: 0CVE-2020-15810 – squid: HTTP Request Smuggling could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15810
An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00017.html https://github.com/squid-cache/squid/security/advisories/GHSA-3365-q9qx-f98m https://lists.debian.org/debian-lts-announce/2020/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BE6FKUN7IGTIR2MEEMWYDT7N5EJJLZI2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMTFLVB7GLRF2C • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
