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

medium Tenable Cloud Security Plugin ID 476894

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 P;2L and P;4L raw decoders can read past the
 end of an input buffer. ImagingRawDecode calculates a packed-pixel row size, while the unpackers read
 separately padded bit planes. A caller can supply a buffer and image dimensions whose accepted size is
 smaller than the unpacker's actual footprint. This can disclose up to three adjacent heap bytes in output
 pixels or crash the process. This issue is fixed in version 13.0.0. (CVE-2026-112394)

Solution

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