+ <p>
+ MLDonkey is a peer-to-peer filesharing client that connects to several
+ different peer-to-peer networks, including Overnet and BitTorrent.
+ </p>
+ </background>
+ <description>
+ <p>
+ The Gentoo MLDonkey ebuild adds a user to the system named "p2p" so
+ that the MLDonkey service can run under a user with low privileges.
+ With older Portage versions this user is created with a valid login
+ shell and no password.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ A remote attacker could log into a vulnerable system as the p2p user.
+ This would require an installed login service that permitted empty
+ passwords, such as SSH configured with the "PermitEmptyPasswords yes"
+ option, a local login console, or a telnet server.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ See Resolution.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ Change the p2p user's shell to disallow login. For example, as root run
+ the following command:
+ </p>
+ <code>
+ # usermod -s /bin/false p2p</code>
+ <p>
+ NOTE: updating to the current MLDonkey ebuild will not remove this
+ vulnerability, it must be fixed manually. The updated ebuild is to
+ prevent this problem from occurring in the future.
+ </p>
