The graphics package has always treated the first "." as delimiting the
extension: for me your example fails in TL'16 and TL'17. Moreover, we've
not changed the filename parsing at all. Can you give \listfiles details
for your two runs?
On the second point, I guess this is an engine issue though if the file
has invalid data in it then all bets are off anyway.
