Details

It was discovered that Pillow incorrectly handled certain image files. If a
user or automated system were tricked into opening a specially-crafted
file, a remote attacker could cause Pillow to crash or hand, resulting in a
denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.04

• python3-pil - 8.1.2-1ubuntu0.1

Ubuntu 20.10

• python3-pil - 7.2.0-1ubuntu0.3

Ubuntu 20.04

• python3-pil - 7.0.0-4ubuntu0.4

Ubuntu 18.04

• python3-pil - 5.1.0-1ubuntu0.6
• python-pil - 5.1.0-1ubuntu0.6

In general, a standard system update will make all the necessary changes.
