CVE-2018-20457
Last modified
CVE-2018-20457 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.86% chance of exploitation in the next 30 days.
