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 in libr/util/strbuf.c via a stack-based buffer over-read) by crafting an input file, a related issue to CVE-2018-20455.

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 en libr/util/strbuf.c mediante una sobrelectura de búfer basada en pila) manipulando un archivo de entradas. Esto está relacionado con CVE-2018-20455.
