✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To reduce exposure, avoid processing untrusted PNG image files with applications that utilize libpng. Restricting the source of PNG images to trusted origins can limit the attack surface.
