CVE-2021-28651 – squid: denial of service in URN processing

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. 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 http://www.openwall.com/lists/oss-security/2023/10/11/3 https://bugs.squid-cache.org/show_bug.cgi?id=5104 https://github.com/squid-cache/squid/security/advisories/GHSA-ch36-9jhx-phm4 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/archives/list/package-announce%40lists.fedoraprojec • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
