CVE-2026-64612
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se encontró una vulnerabilidad en libcupsfilters y cups-filters. La función de lectura de imágenes PNG crea un lector de libpng sin instalar un gestor de recuperación de errores, lo que provoca que el proceso del filtro de imágenes de CUPS se aborte al procesar un archivo PNG malformado. Un atacante no autenticado podría explotar esto al enviar un trabajo de impresión PNG especialmente diseñado, lo que lleva a una denegación de servicio del trabajo de impresión en curso."
