    Summary: PIL and Pillow Vulnerable to Symlink Attack on Tmpfiles

    Details: The (1) `load_djpeg` function in `JpegImagePlugin.py`, (2) `Ghostscript` function in `EpsImagePlugin.py`, (3) `load` function in `IptcImagePlugin.py`, and (4) `_copy` function in `Image.py` in Python Image Library (PIL) 1.1.7 and earlier and Pillow before 2.3.1 do not properly create temporary files, which allow local users to overwrite arbitrary files and obtain sensitive information via a symlink attack on the temporary file.
