It features a very Apache-like configuration syntax, and a highly customizable server infrastructure, including support for multiple 'virtual' FTP servers, anonymous FTP, and permission-based directory visibility. Problem description: kernel < TSL 3.0 > - New upstream. - SECURITY FIX: A vulnerability has been identified which could be exploited by malicious users to bypass security restrictions.
