{"id":"CVE-2023-0217","summary":"NULL dereference validating DSA public key","details":"An invalid pointer dereference on read can be triggered when an\napplication tries to check a malformed DSA public key by the\nEVP_PKEY_public_check() function. This will most likely lead\nto an application crash. This function can be called on public\nkeys supplied from untrusted sources which could allow an attacker\nto cause a denial of service attack.\n\nThe TLS implementation in OpenSSL does not call this function\nbut applications might call the function if there are additional\nsecurity requirements imposed by standards such as FIPS 140-3.","aliases":["GHSA-vxrh-cpg7-8vjr","RUSTSEC-2023-0012"],"modified":"2026-05-18T05:56:23.900797390Z","published":"2023-02-08T19:02:48.524Z","related":["ALSA-2023:0946","CGA-583g-97m7-wqmg","SUSE-SU-2023:0312-1","openSUSE-SU-2024:12716-1"],"database_specific":{"unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.0.8"}]}],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/0xxx/CVE-2023-0217.json","cna_assigner":"openssl"},"references":[{"type":"WEB","url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2023-0003"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/0xxx/CVE-2023-0217.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-0217"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202402-08"},{"type":"ADVISORY","url":"https://www.openssl.org/news/secadv/20230207.txt"},{"type":"FIX","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=23985bac83fd50c8e29431009302b5442f985096"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openssl/openssl","events":[{"introduced":"89cd17a031e022211684eb7eb41190cf1910f9fa"},{"last_affected":"19cc035b6c6f2283573d29c7ea7f7d675cf750ce"}],"database_specific":{"cpe":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"introduced":"3.0.0"},{"last_affected":"3.0.7"}]}}],"versions":["openssl-3.0.7","openssl-3.0.6","openssl-3.0.5","openssl-3.0.4","openssl-3.0.3","openssl-3.0.2","openssl-3.0.1","openssl-3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-0217.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
