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"
