MLDonkey: Information disclosure

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-p2p/mldonkey	< 3.0.0	>= 3.0.0	All supported architectures

Related bugreports: #260072

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

2. Impact Information

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

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.

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

3. Resolution Information

Disable the web interface or restrict access to it.

All MLDonkey users should upgrade to the latest version:

Code Listing 3.1: Resolution

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