CVE-2021-20244

Estado: ModificadaMedia (5.5)—

Se encontró un fallo en ImageMagick en el archivo MagickCore/visual-effects.c. Un atacante que envía un archivo diseñado que es procesado por ImageMagick podría desencadenar un comportamiento indefinido en el formulario de división matemática por cero. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema
