CRITICAL 9.8EPSS 0.55%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
