CVE-2025-12474  (opens in a new tab)

How to fix?

Upgrade Alpine:3.23 libjxl to version 0.11.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libjxl package and not the libjxl package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory.

This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the decoder to omit populating those areas.
