==========================================================================

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

- Ubuntu 23.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in Pillow.

Software Description:
- pillow: Python Imaging Library

Details:

It was discovered that Pillow incorrectly handled certain long text
arguments. An attacker could possibly use this issue to cause Pillow to
consume resources, leading to a denial of service. This issue only affected
Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2023-44271)

Duarte Santos discovered that Pillow incorrectly handled the environment
parameter to PIL.ImageMath.eval. An attacker could possibly use this issue
to execute arbitrary code. (CVE-2023-50447)

Update instructions:

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

Ubuntu 23.10:
   python3-pil                     10.0.0-1ubuntu0.1

Ubuntu 22.04 LTS:
   python3-pil                     9.0.1-1ubuntu0.2

Ubuntu 20.04 LTS:
   python3-pil                     7.0.0-4ubuntu0.8

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