Remote code execution via unbounded register-field parsing
Published Dec 17, 2024 · Updated Dec 18, 2024
Buffer overflow in radare2 5.8.8 allows remote attackers to execute arbitrary code through a crafted GDB register profile. The GDB register-profile parser used unbounded sscanf string conversions for attacker-controlled name, type, and group fields stored in fixed-size buffers. A malicious or compromised GDB remote endpoint can trigger memory corruption when radare2 imports its register description.
