Descriptions

In coders/bmp.c in ImageMagick before 7.0.8-16, an input file can result in an infinite loop and hang, with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.

En coders/bmp.c en ImageMagick en versiones anteriores a la 7.0.8-16, un archivo de entradas puede resultar en un bucle infinito y un bloqueo, con un gran consumo de CPU y memoria. Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo manipulado.
