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"
