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

medium Tenable Cloud Security Plugin ID 476875

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's PdfParser.get_value() can recurse
 without a limit while reading nested PDF objects. The parser follows attacker-controlled arrays and
 dictionaries when an existing PDF is opened for append. An attacker can provide a deeply nested PDF to an
 application that saves an image with PDF append enabled. This can raise an uncaught RecursionError or
 terminate the worker, causing denial of service. This issue is fixed in version 13.0.0. (CVE-2026-112391)

Solution

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