    Published: 25 Dec 2018Last Modified: 7 Aug 2026

    Summary:

    Details: 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.
