CVE-2019-19911: Integer Overflow

First published: Fri Jan 03 2020(Updated: )

A denial of service vulnerability was found in Pillow in versions before 6.2.2, where the FpxImagePlugin.py file calls the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows systems running 32-bit Python, this flaw results in an OverflowError or MemoryError due to the 2 GB limit. On Linux systems running 64-bit Python, this flaw results in the termination of the process by the out-of-memory (OOM) killer. The highest threat from this vulnerability is to system availability.
