CVE-2002-20002 Details
Description
The Net::EasyTCP package before 0.15 for Perl always uses Perl's builtin rand(), which is not a strong random number generator, for cryptographic keys.
A vulnerability exists in the Net::EasyTCP package for Perl, specifically in versions prior to 0.15. The issue arises because the package relies on Perl's built-in random number generator, rand(), which is not suitable for cryptographic purposes, to create cryptographic keys. This could lead to predictable key generation and potential security risks in applications using this module.
Users are advised to upgrade to Net::EasyTCP version 0.15 or later, where the vulnerability has been addressed by implementing a stronger random number generator, Crypt::Random.
