pillow vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
- Ubuntu 14.04 LTS (Available with Ubuntu Pro)

Summary:

Pillow could be made to crash or run programs as an administrator
if it opened a specially crafted file.

Software Description:
- pillow: Python Imaging Library

Details:

Hugo van Kemenade discovered that Pillow was not properly performing
bounds checks when processing an ICC file, which could lead to a buffer
overflow. If a user or automated system were tricked into processing a
specially crafted ICC file, an attacker could possibly use this issue
to cause a denial of service or execute arbitrary code.
