Application interruption via recursive Lua error handling
Published Jan 27, 2026 · Updated Jan 27, 2026
Out-of-bounds write in Gerstrong Commander Genius before Release refs/pull/358/merge allows remote attackers to interrupt application operation. The bundled Lua luaG_runerror path retains a temporary error-message slot while errors recur, exhausting EXTRA_STACK and permitting a write beyond the stack boundary. Exploitation requires a Lua C-stack or string-overflow error to recur; the public record does not explain how remote input reaches that path and reports no data disclosure or modification.
