Ubuntu 20.04 LTS / 22.04 LTS / 23.10 : Pillow vulnerabilities (USN-6618-1)

high Nessus Plugin ID 189830

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6618-1 advisory.

 - An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory.
 This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument. (CVE-2023-44271)

 - Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter). (CVE-2023-50447)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected python3-pil and / or python3-pil.imagetk packages.
