Descriptions

In radare2 through 3.1.3, the assemble function inside libr/asm/p/asm_arm_cs.c allows attackers to cause a denial-of-service (application crash via an r_num_calc out-of-bounds read) by crafting an arm assembly input because a loop uses an incorrect index in armass.c and certain length validation is missing in armass64.c, a related issue to CVE-2018-20459.

En radare2 hasta la versión 3.1.3, la función assemble en libr/asm/p/asm_arm_cs.c permite que los atacantes provoquen una denegación de servicio (cierre inesperado de la aplicación mediante una lectura fuera de límites en r_num_calc) manipulando una entrada de ensamblado de arm debido a que un bucle emplea un índice incorrecto en armass.c y falta cierta validación de longitud en armass64.c. Esto está relacionado con CVE-2018-20459.
