If the JCA key pair generator is not explicitly initialised with DSA parameters, 1.55 and earlier generates a private value assuming a 1024 bit key size. In earlier releases this can be dealt with by explicitly passing parameters to the key pair generator.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-310"],"references":["https://access.redhat.com/errata/RHSA-2018:2669","https://access.redhat.com/errata/RHSA-2018:2927","https://github.com/bcgit/bc-java/commit/50a53068c094d6cff37659da33c9b4505becd389#diff-5578e61500abb2b87b300d3114bdfd7d","https://lists.apache.org/thread.html/708d94141126eac03011144a971a6411fcac16d9c248d1d535a39451%40%3Csolr-user.lucene.apache.org%3E","https://lists.debian.org/debian-lts-announce/2018/07/msg00009.html"],"products":["bouncycastle:bc-java","debian:debian_linux"],"source":"nvd","synced_at":"2026-10-19T20:50:40.212176939+00:00"},"epss":{"cve":"CVE-2016-1000343","score":0.03253,"percentile":0.88343,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rrvx-pwf8-p59p","url":"https://osv.dev/vulnerability/GHSA-rrvx-pwf8-p59p","summary":"In Bouncy Castle JCE Provider the DSA key pair generator generates a weak private key if used with default values","modified":"2025-09-12T20:11:26.404347Z","packages":[{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk14","purl":"pkg:maven/org.bouncycastle/bcprov-jdk14","ranges":["<1.56"],"fixed":["1.56"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk15","purl":"pkg:maven/org.bouncycastle/bcprov-jdk15","ranges":["<1.56"],"fixed":["1.56"]},{"ecosystem":"Maven","name":"org.bouncycastle:bcprov-jdk15on","purl":"pkg:maven/org.bouncycastle/bcprov-jdk15on","ranges":["<1.56"],"fixed":["1.56"]}]}],"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).
