CVE-2022-41318 – squid: buffer-over-read in SSPI and SMB authentication
https://notcve.org/view.php?id=CVE-2022-41318
27 Sep 2022 — A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7. Se descubrió una lectura excesiva del búfer en libntlmauth en Squid 2.5 a 5.6. • http://www.squid-cache.org/Versions/v4/changesets/SQUID-2022_2.patch • CWE-126: Buffer Over-read CWE-190: Integer Overflow or Wraparound •

CVE-2021-28652 – squid: denial of service issue in Cache Manager
https://notcve.org/view.php?id=CVE-2021-28652
26 May 2021 — 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 • CWE-401: Missing Release of Memory after Effective Lifetime •
