On my point-and-shoot camera, green rectangles show up in the viewfinder/display around bright light sources when I frame a shot. What are these boxes indicating, and why does the camera show them?

It is most likely a putting a box around any over-exposed areas. The more conventional approach to this is to shade any area that is overexposed, but putting a box around the area can work too. The reason for this is to highlight areas where image data will be lost.

Those green rectangles are most likely the camera’s way of marking overexposed highlights. Bright light sources can exceed the sensor’s usable range, so the camera highlights those areas to warn that detail may be lost there.
Many cameras show overexposure warnings in different ways, such as blinking highlights or shaded areas; your camera appears to draw boxes instead. It’s a visual aid so you know parts of the image may record as pure white with no recoverable detail.
If you want to reduce this, try lowering the exposure, using exposure compensation, or recomposing so the bright source is less dominant.
