Synopsis
========

A flaw in ProFTPD may allow a local attacker to obtain root privileges.

Background
==========

ProFTPD is a powerful, configurable, and free FTP daemon.

Affected packages
=================

    -------------------------------------------------------------------
     Package          /   Vulnerable   /                    Unaffected
    -------------------------------------------------------------------
  1  net-ftp/proftpd      < 1.3.1_rc1                     >= 1.3.1_rc1

Description
===========

A flaw exists in the mod_ctrls module of ProFTPD, normally used to
allow FTP server administrators to configure the daemon at runtime.

Impact
======

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.

Workaround
==========

Disable mod_ctrls, or ensure only trusted users can access this
feature.

Resolution
==========

All ProFTPD users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.1_rc1"
