<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All gFTP users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-ftp/gftp-2.0.18-r1&quot;</code>
</resolution>
