CVE-2026-64612 (GCVE-0-2026-64612)

Vulnerability from cvelistv5 – Published: 2026-07-20 17:33 – Updated: 2026-07-21 17:31

Title

Libcupsfilters: cups-filters: libcupsfilters: cups image filter process abort via malformed png

Summary

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.

Severity

7.5 (High)
