| Descrição | Duktape's bytecode loader (`duk_api_bytecode.c`) uses the `DUK_ASSERT` macro for bounds checking. In Release builds, `DUK_ASSERT` is defined as a no-op, so the bounds check is completely removed. By crafting bytecode with an inflated `count_instr` field and a truncated buffer ending at the instruction data boundary, the loader reads 4 bytes past the heap allocation, which are then interpreted as bytecode instructions. |
