Summary

Pillow could be made to crash if it received specially crafted input or opened

a specially crafted file.

Software Description:

- pillow: Python Imaging Library compatibility layer

a PNG image could cause the image to have a large size when decompressed,

potentially leading to a denial of service. (CVE-2014-9601)

attacker could use this to cause Pillow to crash, resulting in a denial

of service. (CVE-2014-3589)
