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"
