Hello,

Great articule, but I how some doubts that I want to comment with you all . When information is received from an untrusted source it must be validated prior to processing it. In the case of the aforementioned talkd hole, the daemon should have made sure the path to the terminal file was indeed correct. This could have been done by simply checking the password database, making sure the ownership matched, and that the terminal path did indeed point to a terminal. Later in the FAQ, the concept of the least privilege principle is explained, and it would have worked wonders with the aforementioned security hole.
Many Thanks
