CVE-2026-12205 (opens in a new tab)How to fix?
There is no fixed version for Debian:12 libcrypt-dsa-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcrypt-dsa-perl package and not the libcrypt-dsa-perl package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
