Descriptions
The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.
La función png_err en pngerror.c en libpng v1.0.x antes de v1.0.55, en v1.2.x antes de v1.2.45, en v1.4.x antes de v1.4.8, y en v1.5.x antes de v1.5.4, hace una llamada a la función con un argumento de puntero NULL en lugar de un argumento de cadena vacía, lo cual permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de una imagen PNG creada.
