When endpoint identification is enabled in the BCJSSE and an SSL socket is created without an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address in some situations, opening up a possibility of DNS poisoning.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-297"],"references":["https://github.com/bcgit/bc-java/wiki/CVE%E2%80%902024%E2%80%9034447","https://security.netapp.com/advisory/ntap-20240614-0007/","https://www.bouncycastle.org/latest_releases.html","https://github.com/bcgit/bc-java/wiki/CVE%E2%80%902024%E2%80%9034447","https://security.netapp.com/advisory/ntap-20240614-0007/"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:23.840078609+00:00"},"epss":{"cve":"CVE-2024-34447","score":0.0077,"percentile":0.55659,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4h8f-2wvx-gg5w","url":"https://osv.dev/vulnerability/GHSA-4h8f-2wvx-gg5w","summary":"Bouncy Castle Java Cryptography API vulnerable to DNS poisoning","modified":"2026-09-10T03:50:13.465694760Z","packages":[{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk18on","purl":"pkg:maven/org.bouncycastle/bcprov-jdk18on","ranges":[">=1.61 <1.78"],"fixed":["1.78"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk15to18","purl":"pkg:maven/org.bouncycastle/bcprov-jdk15to18","ranges":[">=1.61 <1.78"],"fixed":["1.78"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk14","purl":"pkg:maven/org.bouncycastle/bcprov-jdk14","ranges":[">=1.61 <1.78"],"fixed":["1.78"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk12","purl":"pkg:maven/org.bouncycastle/bcprov-jdk12","ranges":[">=1.61 <1.78"],"fixed":["1.78"]},{"ecosystem":"Maven","name":"org.bouncycastle:bctls-fips","purl":"pkg:maven/org.bouncycastle/bctls-fips","ranges":["<1.0.19"],"fixed":["1.0.19"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-lts8on","purl":"pkg:maven/org.bouncycastle/bcprov-lts8on","ranges":["<2.73.6"],"fixed":["2.73.6"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk15on","purl":"pkg:maven/org.bouncycastle/bcprov-jdk15on","ranges":[">=1.61 <1.78"],"fixed":["1.78"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
