Crypt::PBKDF2 vulnerabilities

Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks. The use of Perl's built-in eq comparison may allow an attacker to guess the underlying derived key by analyzing timing discrepancies.

Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems.

Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. They use the built-in rand function, which is predictable and unsuitable for cryptography.
