No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Crypt::Password versions through 0.28 for Perl generate insecure random values for salts.

These versions use the built-in rand function, which is predictable and unsuitable for cryptography.
