SCA: security update for Pillow (GHSA-8g5g-8vmr-9782)

critical Tenable Self-Hosted Container Security Plugin ID 476408

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Pillow is a Python imaging library. Prior to 13.0.0, Pillow's JPEG decoder can write a full-width scanline
into a buffer sized for a requested draft scale. ImagingJpegDecode does not verify libjpeg's actual output
width and component count after scaling is requested, and an 8-bit lossless SOF3 JPEG decoded by a build
linked to libjpeg-turbo 3.x can ignore the requested downscaling geometry. An attacker can supply such a
JPEG to an application that uses draft() or thumbnail() to request downscaling. This can corrupt heap
memory, crash the process, or potentially allow code execution. Older libjpeg-turbo 2.x and IJG builds
reject the SOF3 input. This issue is fixed in version 13.0.0. (CVE-2026-112403)

Solution

Update the Pillow library and its related packages to version 13.0.0 or later.
