  "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.",
