Synopsis
========

A Denial of Service vulnerability was discovered in EnergyMech that is
easily exploitable via IRC.

Background
==========

EnergyMech is an IRC bot programmed in C.

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

    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-irc/emech       < 3.0.2                              >= 3.0.2

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

A bug in EnergyMech fails to handle empty CTCP NOTICEs correctly, and
will cause a crash from a segmentation fault.

Impact
======

By sending an empty CTCP NOTICE, a remote attacker could exploit this
vulnerability to cause a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All EnergyMech users should update to the latest stable version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/emech-3.0.2"
