DESCRIPTION:
A vulnerability has been discovered in FTPShell Client, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing
FTP responses and can be exploited to cause a stack-based buffer
overflow via an overly long PWD response.

Successful exploitation allows execution of arbitrary code, but
requires that the user is tricked into connecting to a malicious FTP
server.

The vulnerability is confirmed in version 5.1. Other versions may
also be affected.

SOLUTION:
Do not connect to untrusted FTP servers.
