MLDonkey: Information disclosure

Background

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

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"
