<p>
ProFTPD is a powerful, configurable, and free FTP daemon.
</p>
</background>
<description>
<p>
A flaw exists in the mod_ctrls module of ProFTPD, normally used to
allow FTP server administrators to configure the daemon at runtime.
</p>
</description>
<impact type="high">
<p>
An FTP server administrator permitted to interact with mod_ctrls could
potentially compromise the ProFTPD process and execute arbitrary code
with the privileges of the FTP Daemon, which is normally the root user.
</p>
</impact>
<workaround>
<p>
Disable mod_ctrls, or ensure only trusted users can access this
feature.
</p>
</workaround>
<resolution>
<p>
All ProFTPD users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-ftp/proftpd-1.3.1_rc1&quot;</code>
</resolution>
