Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
A bug in EnergyMech fails to handle empty CTCP NOTICEs correctly, and
will cause a crash from a segmentation fault.
Impact
=3D=3D=3D=3D=3D=3D
By sending an empty CTCP NOTICE, a remote attacker could exploit this
vulnerability to cause a Denial of Service.

There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
