Synopsis
========

A vulnerability in the MLDonkey web interface allows remote attackers
to disclose arbitrary files.

Background
==========

MLDonkey is a multi-network P2P application written in Ocaml, coming
with its own Gtk GUI, web and telnet interface.

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

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-p2p/mldonkey       < 3.0.0                           >= 3.0.0

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

Michael Peselnik reported that src/utils/lib/url.ml in the web
interface of MLDonkey does not handle file names with leading double
slashes properly.

Impact
======

A remote attacker could gain access to arbitrary files readable by the
user running the application.

Workaround
==========

Disable the web interface or restrict access to it.

Resolution
==========

All MLDonkey users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-p2p/mldonkey-3.0.0"
