Net::EasyTCP encryption key prediction vulnerability
Original title: USN-8985-1: Net::EasyTCP vulnerability
Net::EasyTCP weak rand() function allows key prediction and sensitive data exposure.
It was discovered that Net::EasyTCP used the built-in Perl rand() function to generate encryption keys when no strong randomization module was present. An attacker could possibly use this issue to predict the keys and obtain sensitive information. Ubuntu Security Notice USN-8985-1.
