Gee, I don't know if this is a fire safety issue or not.

An in-law replaced the halogen flood light unit in my backyard with one that uses a movement sensor.

Anyway, the mounting configuration of the new unit is not standard which means that only one screw could be used to attach the unit to the wall. For this reason I noticed that the new unit does not sit flush to the wall (an open exposed area under the eaves) and that at the bottom of the unit I see a strand of what appears to be twisted copper wire. Could this expose wire be a potential fire hazard?

Chances are, what you see is the ground wire. It is NOT a current carrier (when installed correctly) and therefore is not insulated. It IS SAFE for it to be exposed.
If the wire you see is the hot or neutral wire, it should be covered with insulation up to the point where it is twisted together (with the fixture's hot or neutral), and the "twist" should be covered with a wire nut or similar insulated device.

Marc-First of all the fixture is mounted outdoors, this makes it a wet location and if sheathed electrical cable was used for the intallation this is wrong, minimum should have been UF cable.
Any exposed wiring can be a hazard, especially if it has a plastic sheath, it MUST BE PROTECTED.
You said only one screw is holding the fixture into place which means that the manufactures instructions were not followed.
Your question was can this be a fire-hazard, absolutely possible. Especially if the wiring treminations are exposed to the weather, wire-nutted connections have a tendency to corrode wheen exposed the elements corrosion causes high resistance points and this causes arching. Best to get it fixed correctly.
