{"id":"DEBIAN-CVE-2026-12205","details":"Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery.  Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it.  The first sign() on a Key object picks a nonce, and every later sign() on that same object reuses it, producing an identical \"r\".  Keys used to sign more than once with an affected version should be considered compromised.","modified":"2026-09-14T17:01:44.408983680Z","published":"2026-06-15T23:16:43.150Z","upstream":["CVE-2026-12205"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-12205"}],"affected":[{"package":{"name":"libcrypt-dsa-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libcrypt-dsa-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.17-5","1.19-1","1.20-1","1.21-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12205.json"}},{"package":{"name":"libcrypt-dsa-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libcrypt-dsa-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.19-1","1.20-1","1.21-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12205.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:H/I:H/A:N"}]}
