CVE-2018-20459 is an out-of-bounds read vulnerability affecting radare2 versions through 3.1.3, specifically within the armass_assemble function. An unauthenticated attacker can trigger a denial-of-service (application crash) by providing a specially crafted ARM assembly input, exploiting incorrect loop indexing and missing length validation. Rated Medium severity (CVSS 5.5), this vulnerability requires user interaction (UI:R) and local access (AV:L), leading to high availability impact (A:H). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
