{"id":"ALPINE-CVE-2023-0464","details":"A security vulnerability has been identified in all supported versions\n\nof OpenSSL related to the verification of X.509 certificate chains\nthat include policy constraints.  Attackers may be able to exploit this\nvulnerability by creating a malicious certificate chain that triggers\nexponential use of computational resources, leading to a denial-of-service\n(DoS) attack on affected systems.\n\nPolicy processing is disabled by default but can be enabled by passing\nthe `-policy' argument to the command line utilities or by calling the\n`X509_VERIFY_PARAM_set1_policies()' function.","modified":"2026-09-15T08:17:48.351702596Z","published":"2023-03-22T17:15:13.130Z","upstream":["CVE-2023-0464"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-0464"}],"affected":[{"package":{"name":"openssl","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.1.1t-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.1.1t-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.1.1t-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.0.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"3.1.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl3","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/openssl3?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.json"}},{"package":{"name":"openssl3","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/openssl3?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-0464.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"}]}
