Since it's data it should not be a problem unless there's a bug in the parser.. Of course that happens but unless your site is insanely secure there are probably more pressing problems.. It might be a good idea to run it through ImageMageick or something once since that, if I recall correctly, fixes a problem with stacking code(?) in GiFs. But if there's a parsing bug in ImageMagick you just made their problem your problem. Scanning with AV seems kind of useless.. if there's code there wouldn't it be custom?
