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 •

CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 0CVE-2023-46724 – SQUID-2023:4 Denial of Service in SSL Certificate validation
https://notcve.org/view.php?id=CVE-2023-46724
Squid is a caching proxy for the Web. Due to an Improper Validation of Specified Index bug, Squid versions 3.3.0.1 through 5.9 and 6.0 prior to 6.4 compiled using `--with-openssl` are vulnerable to a Denial of Service attack against SSL Certificate validation. This problem allows a remote server to perform Denial of Service against Squid Proxy by initiating a TLS Handshake with a specially crafted SSL Certificate in a server certificate chain. This attack is limited to HTTPS and SSL-Bump. This bug is fixed in Squid version 6.4. • http://www.squid-cache.org/Versions/v5/SQUID-2023_4.patch http://www.squid-cache.org/Versions/v6/SQUID-2023_4.patch https://github.com/squid-cache/squid/commit/b70f864940225dfe69f9f653f948e787f99c3810 https://github.com/squid-cache/squid/security/advisories/GHSA-73m6-jm96-c6r3 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A5QASTMCUSUEW3UOMKHZJB3FTONWSRXS https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MEV66D3PAAY6K7TWDT3WZBLCPLASFJDC https: • CWE-125: Out-of-bounds Read CWE-129: Improper Validation of Array Index CWE-295: Improper Certificate Validation CWE-786: Access of Memory Location Before Start of Buffer CWE-823: Use of Out-of-range Pointer Offset CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •

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.
