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." } ], "source": { "advisory": "GHSA-73m6-jm96-c6r3", "discovery": "UNKNOWN" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T20:53:20.863Z" }, "title": "CVE Program Container", "references": [ { "name": "https://github.com/squid-cache/squid/security/advisories/GHSA-73m6-jm96-c6r3", "tags": [ "x_refsource_CONFIRM", "x_transferred" ], "url": "https://github.com/squid-cache/squid/security/advisories/GHSA-73m6-jm96-c6r3" }, { "name": "https://github.com/squid-cache/squid/commit/b70f864940225dfe69f9f653f948e787f99c3810", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/squid-cache/squid/commit/b70f864940225dfe69f9f653f948e787f99c3810" }, { "name": "http://www.squid-cache.org/Versions/v5/SQUID-2023_4.patch", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "http://www.squid-cache.org/Versions/v5/SQUID-2023_4.patch" }, { "name": "http://www.squid-cache.org/Versions/v6/SQUID-2023_4.patch", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "http://www.squid-cache.org/Versions/v6/SQUID-2023_4.patch" }, { "url": "https://security.netapp.com/advisory/ntap-20231208-0001/", "tags": [ "x_transferred" ] }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MEV66D3PAAY6K7TWDT3WZBLCPLASFJDC/", "tags": [ "x_transferred" ] }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/A5QASTMCUSUEW3UOMKHZJB3FTONWSRXS/", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-09-05T20:13:11.511935Z", "id": "CVE-2023-46724", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-05T20:13:29.792Z" } } ] } }
