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.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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.
