Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch."}, {"lang": "es", "value": "ImageMagick es un software libre y de c\u00f3digo abierto utilizado para editar y manipular im\u00e1genes digitales. Antes de las versiones 7.1.2-15 y 6.9.13-40, existe una vulnerabilidad de lectura excesiva de b\u00fafer de pila en el gestor del formato de imagen DJVU.
