https://notcve.org/view.php?id=CVE-2019-18860
20 Mar 2020 — Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi. Squid versiones anteriores a 4.9, cuando determinados navegadores web son usados, maneja inapropiadamente HTML en el parámetro host (también se conoce como hostname) en el archivo cachemgr.cgi. A flaw was found in squid. Squid, when certain web browsers are used, mishandles HTML in the host parameter to cachemgr.cgi which could result in squid behaving in unsecure way.

CVE-2020-8517 – Gentoo Linux Security Advisory 202003-34
https://notcve.org/view.php?id=CVE-2020-8517
04 Feb 2020 — An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.

CVE-2019-18679 – squid: Information Disclosure issue in HTTP Digest Authentication
https://notcve.org/view.php?id=CVE-2019-18679
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. Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8. • http://www.squid-cache.org/Advisories/SQUID-2019_11.txt • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2019-12529 – squid: Out of bounds read in Proxy-Authorization header causes DoS
https://notcve.org/view.php?id=CVE-2019-12529
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 •
