CVE-2021-31808 – squid: integer overflow in HTTP Range header
https://notcve.org/view.php?id=CVE-2021-31808
26 May 2021 — 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 • CWE-190: Integer Overflow or Wraparound •

26 May 2021 — 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.

CVE-2021-28651 – squid: denial of service in URN processing
https://notcve.org/view.php?id=CVE-2021-28651
26 May 2021 — 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.

09 Mar 2021 — Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of an out-of-bounds read in WCCP protocol data. This can be leveraged as part of a chain for remote code execution as nobody. Squid versiones hasta 4.14 y 5.xa 5.0.5, en algunas configuraciones, permite la divulgación de información debido a una lectura fuera de límites en los datos del protocolo WCCP.

CVE-2020-15811 – squid: HTTP Request Splitting could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15811
27 Aug 2020 — An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting 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 browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') CWE-697: Incorrect Comparison •

CVE-2020-15810 – squid: HTTP Request Smuggling could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15810
27 Aug 2020 — 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 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

CVE-2019-12520 – squid: Improper input validation in request allows for proxy manipulation
https://notcve.org/view.php?id=CVE-2019-12520
15 Apr 2020 — An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. • http://www.squid-cache.org/Versions/v4 • CWE-20: Improper Input Validation •
