Here is an example of secure code that properly validates the length of the input data:
A code review of the vsftpd 2.0.8 source code reveals that the vulnerability was caused by a lack of proper bounds checking on the input data. The code did not properly validate the length of the input data, allowing an attacker to overflow a buffer and execute malicious code.
The exploit worked by overflowing a buffer in the vsftpd server, which allowed the attacker to execute a shellcode, a piece of code that spawns a shell, giving the attacker remote access to the server. The exploit was relatively simple to execute, requiring only a basic understanding of FTP and network protocols.
