CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2023-5824 – Squid: dos against http and https
https://notcve.org/view.php?id=CVE-2023-5824
Squid is vulnerable to Denial of Service attack against HTTP and HTTPS clients due to an Improper Handling of Structural Elements bug. Squid es vulnerable a ataques de Denegación de Servicio contra clientes HTTP y HTTPS debido a un error en el manejo inadecuado de elementos estructurales. A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service. • https://access.redhat.com/errata/RHSA-2023:7465 https://access.redhat.com/errata/RHSA-2023:7668 https://access.redhat.com/errata/RHSA-2024:0072 https://access.redhat.com/errata/RHSA-2024:0397 https://access.redhat.com/errata/RHSA-2024:0771 https://access.redhat.com/errata/RHSA-2024:0772 https://access.redhat.com/errata/RHSA-2024:0773 https://access.redhat.com/errata/RHSA-2024:1153 https://access.redhat.com/security/cve/CVE-2023-5824 https://bugzilla.redhat.com/show • CWE-755: Improper Handling of Exceptional Conditions •

SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems. SQUID es vulnerable al contrabando de solicitudes HTTP, causado por la indulgencia de los decodificadores fragmentados, lo que permite a un atacante remoto realizar el contrabando de solicitudes/respuestas a través del firewall y los sistemas de seguridad frontales. • https://access.redhat.com/errata/RHSA-2023:6266 https://access.redhat.com/errata/RHSA-2023:6267 https://access.redhat.com/errata/RHSA-2023:6268 https://access.redhat.com/errata/RHSA-2023:6748 https://access.redhat.com/errata/RHSA-2023:6801 https://access.redhat.com/errata/RHSA-2023:6803 https://access.redhat.com/errata/RHSA-2023:6804 https://access.redhat.com/errata/RHSA-2023:6810 https://access.redhat.com/errata/RHSA-2023:7213 https://access.redhat.com/security/cve&# • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 0CVE-2022-41318 – squid: buffer-over-read in SSPI and SMB authentication
https://notcve.org/view.php?id=CVE-2022-41318
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 http://www.squid-cache.org/Versions/v5/changesets/SQUID-2022_2.patch https://github.com/squid-cache/squid/security/advisories/GHSA-394c-rr7q-6g78 https://www.openwall.com/lists/oss-security/2022/09/23/2 https://access.redhat.com/security/cve/CVE-2022-41318 https://bugzilla.redhat.com/show_bug.cgi?id=2129771 • CWE-126: Buffer Over-read CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2021-33620
Squid before 4.15 and 5.x before 5.0.6 allows remote servers to cause a denial of service (affecting availability to all clients) via an HTTP response. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent by the server. Squid versiones anteriores a 4.15 y versiones 5.x anteriores a 5.0.6, permite a servidores remotos causar una denegación de servicio (afectando la disponibilidad para todos los clientes) por medio de una respuesta HTTP. El desencadenante del problema es un encabezado que puede esperarse que se presente en el tráfico HTTP sin ninguna intención maliciosa por parte del servidor An input validation flaw was found in Squid. This issue could allow a remote server to perform a denial of service against all clients using the proxy when delivering HTTP response messages. • http://seclists.org/fulldisclosure/2023/Oct/14 http://www.openwall.com/lists/oss-security/2023/10/11/3 http://www.squid-cache.org/Versions/v4/changesets/squid-4-1e05a85bd28c22c9ca5d3ac9f5e86d6269ec0a8c.patch http://www.squid-cache.org/Versions/v5/changesets/squid-5-8af775ed98bfd610f9ce762fe177e01b2675588c.patch https://github.com/squid-cache/squid/security/advisories/GHSA-572g-rvwr-6c7f https://lists.debian.org/debian-lts-announce/2021/06/msg00014.html https://lists.fedoraproject.org/archives/list/package-a • CWE-20: Improper Input Validation •
