https://notcve.org/view.php?id=CVE-2023-46728
Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a NULL pointer dereference bug Squid is vulnerable to a Denial of Service attack against Squid's Gopher gateway. The gopher protocol is always available and enabled in Squid prior to Squid 6.0.1. Responses triggering this bug are possible to be received from any gopher server, even those without malicious intent. Gopher support has been removed in Squid version 6.0.1. • https://github.com/squid-cache/squid/commit/6ea12e8fb590ac6959e9356a81aa3370576568c3 https://github.com/squid-cache/squid/security/advisories/GHSA-cg5h-v6vc-w33f 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://security.netapp.com/advisory/ntap-20231214-0006 https://access.redhat.com/security/cve/CVE-2023-46728 https://bugzilla.r • CWE-476: NULL Pointer Dereference •

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 •
