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. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. Those who you use a prepackaged version of Squid should refer to the package vendor for availability information on updated packages." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-125: Out-of-bounds Read", "cweId": "CWE-125" } ] }, { "description": [ { "lang": "eng", "value": "CWE-129: Improper Validation of Array Index", "cweId": "CWE-129" } ] }, { "description": [ { "lang": "eng", "value": "CWE-786: Access of Memory Location Before Start of Buffer", "cweId": "CWE-786" } ] }, { "description": [ { "lang": "eng", "value": "CWE-823: Use of Out-of-range Pointer Offset", "cweId": "CWE-823" } ] }, { "description": [ { "lang": "eng", "value": "CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input", "cweId": "CWE-1285" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "squid-cache", "product": { "product_data": [ { "product_name": "squid", "version": { "version_data": [ { "version_affected": "=", "version_value": ">= 3.3.0.1, < 6.4" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://github.com/squid-cache/squid/security/advisories/GHSA-73m6-jm96-c6r3", "refsource": "MISC", "name": "https://github.com/squid-cache/squid/security/advisories/GHSA-73m6-jm96-c6r3" }, { "url": "https://github.com/squid-cache/squid/commit/b70f864940225dfe69f9f653f948e787f99c3810", "refsource": "MISC", "name": "https://github.com/squid-cache/squid/commit/b70f864940225dfe69f9f653f948e787f99c3810" }, { "url": "http://www.squid-cache.org/Versions/v5/SQUID-2023_4.patch", "refsource": "MISC", "name": "http://www.squid-cache.org/Versions/v5/SQUID-2023_4.patch" }, { "url": "http://www.squid-cache.org/Versions/v6/SQUID-2023_4.patch", "refsource": "MISC", "name": "http://www.squid-cache.org/Versions/v6/SQUID-2023_4.patch" }, { "url": "https://security.netapp.com/advisory/ntap-20231208-0001/", "refsource": "MISC", "name": "https://security.netapp.com/advisory/ntap-20231208-0001/" }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MEV66D3PAAY6K7TWDT3WZBLCPLASFJDC/", "refsource": "MISC", "name": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MEV66D3PAAY6K7TWDT3WZBLCPLASFJDC/" }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A5QASTMCUSUEW3UOMKHZJB3FTONWSRXS/", "refsource": "MISC", "name": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A5QASTMCUSUEW3UOMKHZJB3FTONWSRXS/" } ] }, "source": { "advisory": "GHSA-73m6-jm96-c6r3", "discovery": "UNKNOWN" }, "impact": { "cvss": [ { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8.6, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H", "version": "3.1" } ] } }
