Descriptions

In ImageMagick 7.0.7-29 and earlier, a missing NULL check in ReadOneJNGImage in coders/png.c allows an attacker to cause a denial of service (WriteBlob assertion failure and application exit) via a crafted file.

En ImageMagick 7.0.7-29 y anteriores, la falta de una comprobación NULL en ReadOneJNGImage en coders/png.c permite que un atacante provoque una denegación de servicio (fallo de aserción en WriteBlob y salida de la aplicación) mediante un archivo manipulado.
