USN-6744-1 fixed a vulnerability in Pillow (Python 3). This update
provides the corresponding updates for Pillow (Python 2) in
Ubuntu 20.04 LTS.

Original advisory details:

Hugo van Kemenade discovered that Pillow was not properly performing
bounds checks when processing an ICC file, which could lead to a buffer

specially crafted ICC file, an attacker could possibly use this issue
to cause a denial of service or execute arbitrary code.
