Title
Net::Xero 0.044 and earlier for Perl uses insecure rand() function for cryptographic functions
Summary
Net::Xero 0.044 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Net::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
