Chainguard: openstack-horizon-2025.2: security update to 25.5.2_git20260914-r12

medium Tenable Self-Hosted Container Security Plugin ID 476881

Description

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

 - Pillow is a Python imaging library. From 9.2.0 until 13.0.0, Pillow performs quadratic copying when saving
 a GIF with a long comment. _get_global_header() repeatedly copies portions of comment data while
 assembling the global header, including comments retained from an untrusted input image. An attacker can
 supply an image with a large GIF comment to an application that saves it as GIF. This can consume
 excessive CPU and delay or deny service. This issue is fixed in version 13.0.0. (CVE-2026-112891)

Solution

Update the openstack-horizon-2025.2 library and its related packages to version 25.5.2_git20260914-r12 or later.
