Descriptions

ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file.

ImageMagick 7.0.7-26 Q16 tiene una iteración excesiva en las funciones DecodeLabImage y EncodeLabImage (coders/tiff.c), lo que resulta en un bloqueo de varios minutos con un archivo PoC pequeño. Los atacantes remotos podrían aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo tiff manipulado.
