CVE-2011-5166 describes multiple stack-based buffer overflow vulnerabilities in KnFTP 1.0.0. The vulnerabilities are triggered when the application receives overly long input strings to any of 33 different FTP commands, including USER, PASS, QUIT, PORT, PASV, and others. The vulnerable code fails to properly check the length of user-supplied input before copying it to stack-allocated buffers, leading to the possibility of overwriting the return address or other control data on the stack.
