Maybe it is something wrong on my setup, but never seen that Pillow had problems with jpeg files.
Unfortunately currently has no free time to dive and debug/fix it myself.

I will just create an issue, feel free to close it, if after test there will be no problem found.

What are your OS, Python and Pillow versions?

• OS: macOS 14
• Python: 3.11.6
• Pillow: 10.2 / 10.3.0.dev0

from PIL import Image, ImageSequence

if __name__ == "__main__":
    i = Image.open("bad.jpeg")
    for b in ImageSequence.Iterator(i):
        print(b.getexif())  # SyntaxError: not a TIFF file (header b'http://n' not valid)

from PIL import Image

if __name__ == "__main__":
    i = Image.open("bad.jpeg")
    i.show() # OSError: image file is truncated (664585 bytes not processed)
