Overview

Pillow is a Python Imaging Library (Fork).

Affected versions of this package are vulnerable to Symlink attacks due to insecurely creating temporary files. 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 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.
