Remediation

Vendor Workaround

To mitigate this issue, avoid opening or processing untrusted APNG (Animated Portable Network Graphics) image files with GIMP. Since the vulnerability is triggered by malformed APNG content, restricting interaction with such files will prevent the `file-png` plugin from crashing. If the plugin crashes, restarting GIMP may be necessary to restore full functionality.
