<description>
|
|
<p>
|
|
The 'mget' function in cmds.c lacks validation of the filenames
|
|
that are supplied by the server.
|
|
</p>

</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker running an FTP server could supply clients with
|
|
malicious filenames, potentially allowing the overwriting of arbitrary
|
|
files with the permission of the connected user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All tnftp users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-ftp/tnftp-20050103"</code>
