Data::Entropy for Perl 0.007 and earlier use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Weakness
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.
