Crypt::PasswdMD5 versions through 1.42 for Perl generates insecure random values for salts. The built-in rand function is predictable, and unsuitable for cryptography.

The version of perl-Crypt-PasswdMD5 installed on the remote host is prior to 1.3-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3343 advisory.
