Doc Text:
A flaw was found in Crypt::PasswdMD5 for Perl. This component generates insecure random values for cryptographic salts, which are used to strengthen password hashes. The built-in `rand` function, used for generating these salts, is predictable and not suitable for cryptographic purposes. This vulnerability could allow an attacker to more easily crack password hashes, potentially leading to unauthorized access or information disclosure.

Description OSIDB Bzimport 2026-05-08 18:01:36 UTC
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.
