I just looked up some info on the Lunar Orbiter program. The camera system was a little complicated. The exposures were taken on film, the film was developed onboard, then fed across a scanner to digitize the image for transmission. The film was also moved to keep the image steady as the spacecraft moved.
So artifacts could potentially result from the exposure, the film handling, the scanning or the transmission.
I noticed the spot is dissimilarly white from the rest of the picture, and the top of it lines up with one of the many faint horizontal streaks that are visible in the dark portions of the image. I'd guess it's related to whatever caused those, and their apparently perfect horizontal alignment suggests to me they were from the scanning process.
Of course, based on the shape alone, it also has a bit of an interesting resemblance to sasquatch...
