CVE-2026-40918

A flaw was found in GIMP. Processing a specially crafted PVR image file with large dimensions can lead to a denial of service (DoS). This occurs due to a stack-based buffer overflow and an out-of-bounds read in the PVR image loader, causing the application to crash. Systems that process untrusted PVR image files are affected.

Summary		(es) Se encontró un fallo en GIMP. El procesamiento de un archivo de imagen PVR especialmente diseñado con grandes dimensiones puede provocar una denegación de servicio (DoS). Esto ocurre debido a un desbordamiento de búfer basado en pila y una lectura fuera de límites en el cargador de imágenes PVR, lo que provoca el bloqueo de la aplicación. Los sistemas que procesan archivos de imagen PVR no confiables se ven afectados.
