{"id":"ALPINE-CVE-2023-46724","details":"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. 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.","modified":"2026-09-15T08:17:48.407618190Z","published":"2023-11-01T20:15:08.800Z","upstream":["CVE-2023-46724"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-46724"}],"affected":[{"package":{"name":"squid","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}},{"package":{"name":"squid","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/squid?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.3.0.1"},{"fixed":"6.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-46724.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
