Synopsis
========

gFTP is vulnerable to directory traversal attacks, possibly leading to
the creation or overwriting of arbitrary files.

Background
==========

gFTP is a GNOME based, multi-threaded file transfer client.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-ftp/gftp < 2.0.18-r1 >= 2.0.18-r1

Description
===========

gFTP lacks input validation of filenames received by remote servers.

Impact
======

An attacker could entice a user to connect to a malicious FTP server
and conduct a directory traversal attack by making use of specially
crafted filenames. This could lead to arbitrary files being created or
overwritten.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All gFTP users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/gftp-2.0.18-r1"
