Descriptions

In GraphicsMagick 1.3.31, the ReadDIBImage function of coders/dib.c has a vulnerability allowing a crash and denial of service via a dib file that is crafted to appear with direct pixel values and also colormapping (which is not available beyond 8-bits/sample), and therefore lacks indexes initialization.

En GraphicsMagick 1.3.31, la función ReadDIBImage de coders/dib.c tiene una vulnerabilidad que permite un cierre inesperado y una denegación de servicio (DoS) mediante un archivo dib que está manipulado para que aparezca con valores de píxel directos, así como mapeo por color (que no está disponible más allá de las muestras de 8 bits) y, por lo tanto, carece de indexación.
