Hi,

The following vulnerability was published for libcupsfilters.

CVE-2026-64612[0]:
| A flaw was found in libcupsfilters and cups-filters. The PNG image
| reading function creates a libpng reader without installing an error
| recovery handler, causing the CUPS image filter process to abort
| when processing a malformed PNG file. An unauthenticated attacker
| could exploit this by submitting a specially crafted PNG print job,
| leading to denial of service of the in-flight print job.
