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

high Tenable Self-Hosted Container Security Plugin ID 476878

Description

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

 - Pillow is a Python imaging library. From 5.1.0 until 13.0.0, Pillow takes quadratic time to reserve PDF
 object identifiers when saving many frames with save_all enabled. PdfParser.next_object_id() repeatedly
 rebuilds and scans all previously reserved identifiers for every object. An attacker can supply a multi-
 frame image, including a small APNG with a large declared frame count, to an application that converts it
 to a multipage PDF. This can consume excessive CPU and deny service. This issue is fixed in version
 13.0.0. (CVE-2026-112894)

Solution

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