Summary
It was discovered that Crypt-SaltedHash incorrectly generated salts using a
cryptographically weak pseudo-random number generator. An attacker could
possibly use this issue to predict generated salts, leading to a weakening
of cryptographic protections.

Vulnerabilities 1
-
Critical 9.1
Crypt::SaltedHash versions through 0.09 for Perl generate insecure random values for salts
Crypt::SaltedHash versions through 0.09 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography.
