Descriptions

In radare2 prior to 3.1.1, the parseOperand function inside libr/asm/p/asm_x86_nz.c may allow attackers to cause a denial of service (application crash via a stack-based buffer overflow) by crafting an input file, a related issue to CVE-2018-20456.

En radare2, en versiones anteriores a la 3.1.1, la función parseOperand en libr/asm/p/asm_x86_nz.c podría permitir que los atacantes provoquen una denegación de servicio (cierre inesperado de la aplicación mediante un desbordamiento de búfer basado en pila) manipulando un archivo de entradas. Esto está relacionado con CVE-2018-20456.
