"value": "radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Lua 5.3 bytecode function parser was vulnerable because the Lua 5.3 bytecode function parser read fixed function-metadata fields immediately after a function-name string without checking the remaining buffer length. The vulnerability is triggered by opening or inspecting a crafted Lua 5.3 bytecode file whose function-name string ends at the input-buffer boundary. The parser read two integers and three one-byte fields beyond the allocated input buffer. This can cause invalid parser results or process termination; no attacker-observable memory disclosure has been demonstrated. This issue is fixed in version 6.2.0."
