DESCRIPTION:
gsicht has discovered a vulnerability in RobotFTP Server, which can
be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the handling
of received data prior to authentication. This can be exploited to
cause a buffer overflow by first attempting to login with an invalid
username (about 50 characters long) and then afterwards sending a
large amount of data (about 2500 characters).

Successful exploitation may allow execution of arbitrary code with
the privileges of the FTP server.

The vulnerability has been confirmed in version 1.0 (also mentioned
