{"id":"DEBIAN-CVE-2016-1000343","details":"In the Bouncy Castle JCE Provider version 1.55 and earlier the DSA key pair generator generates a weak private key if used with default values. 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.","modified":"2026-09-01T16:04:06.283555414Z","published":"2018-06-04T13:29:00.437Z","upstream":["CVE-2016-1000343"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2016-1000343"}],"affected":[{"package":{"name":"bouncycastle","ecosystem":"Debian:12","purl":"pkg:deb/debian/bouncycastle?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.56-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-1000343.json"}},{"package":{"name":"bouncycastle","ecosystem":"Debian:13","purl":"pkg:deb/debian/bouncycastle?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.56-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-1000343.json"}},{"package":{"name":"bouncycastle","ecosystem":"Debian:14","purl":"pkg:deb/debian/bouncycastle?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.56-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-1000343.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
