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.","published":"2026-07-20T18:16:56.000Z","lastModified":"2026-10-24T16:10:00.000Z","status":"Awaiting Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-248"],"affected":[],"epss":{"score":0.00704,"percentile":0.53107,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%).
