SCA: security update for Pillow (GHSA-654x-cwwv-5j9c)

medium Tenable Self-Hosted Container Security Plugin ID 477217

Description

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

 - Pillow is a Python imaging library. From 11.2.1 until 13.0.0, Arrow export assumes that an image's rows
 are tightly contiguous and exports from im->blocks[0].ptr even when PILLOW_ALIGNMENT makes
 aligned_linesize include row padding or an aligned offset before the first row. The resulting Arrow buffer
 can include uninitialized padding, bytes preceding the first row, or stale heap contents from previously
 freed images. Applications that configure alignment and export images to Arrow can therefore disclose one
 user's pixels or other process memory to another user. This issue is fixed in version 13.0.0.
 (CVE-2026-114501)

Solution

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