Buffer overflow in LeapFTP 2.7.3.600 allows remote FTP servers to execute arbitrary code via a long IP address response to a PASV request.

Buffer overflow in LeapFTP allows remote attackers to execute arbitrary code via a long Host string in a Site Queue (.lsq) file.

LeapFTP < 3.1.x Stack Buffer Overflow

LeapFTP < 3.1.x contains a stack-based buffer overflow vulnerability in its FTP client parser. When the client receives a directory listing containing a filename longer than 528 bytes, the application fails to properly bound-check the input and overwrites the Structured Exception Handler (SEH) chain. This allows an attacker operating a malicious FTP server to execute arbitrary code on the victim’s machine when the file is listed or downloaded.
