CVE-2023-27590

Process memory corruption via unbounded profile fields

Published Mar 14, 2023 · Updated Feb 25, 2025

Stack-based buffer overflow in Rizin 0.5.1 and earlier allows context-dependent attackers to corrupt memory via a crafted GDB register profile. In gdb_to_rz_profile, sscanf uses unrestricted %s conversions to copy name, type, and groups tokens into fixed-size stack arrays. Exploitation requires a user to load an untrusted profile with drpg or arpg; the overflow can crash the process or corrupt its memory.
