DESCRIPTION:
Tan Chew Keong has reported a vulnerability in AceFTP, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an input validation error when
downloading directories containing files with directory traversal
specifiers in the filename. This can be exploited to download files
to an arbitrary location on a user's system.

Successful exploitation requires that the user is tricked into
connecting and downloading a directory from a malicious FTP server.

The vulnerability is reported in version 3.80.3. Other versions may
also be affected.

SOLUTION:
Do not download directories from untrusted FTP servers.
