https://notcve.org/view.php?id=CVE-2020-8449
04 Feb 2020 — An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters. Se detectó un problema en Squid versiones anteriores a 4.10. Debido a una comprobación de entrada incorrecta, puede interpretar las peticiones HTTP diseñadas de manera no prevista para acceder a recursos del servidor prohibidos por parte de los filtros de seguridad anteriores. A flaw was found in squid. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00012.html • CWE-20: Improper Input Validation CWE-668: Exposure of Resource to Wrong Sphere •

https://notcve.org/view.php?id=CVE-2019-12526
26 Nov 2019 — An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.

https://notcve.org/view.php?id=CVE-2019-12523
26 Nov 2019 — An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost.

26 Nov 2019 — An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.

https://notcve.org/view.php?id=CVE-2019-18678
26 Nov 2019 — An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. • http://www.squid-cache.org/Advisories/SQUID-2019_10.txt • CWE-20: Improper Input Validation CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

26 Nov 2019 — An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.

11 Jul 2019 — An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as wel... • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

11 Jul 2019 — An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
