Version 0.0.2 has a 1-byte heap overflow in `rt_copy_memory`, which unconditionally wrote a null terminator at `dst[len]`. When `len` equals the size of the destination buffer (256 bytes), that extra `'\\0'` write overruns the buffer by one byte. To avoid breaking existing callers or changing the public API, the patch in commit fb7b7f658327f659c6a6da1af151cb389c2ca4ee takes a minimal approach: it simply removes the overflow-causing line without adding bounds checks or altering the function signature."},{"lang":"es","value":"NeKernal es una pila de sistema operativo libre y de código abierto. La versión 0.0.2 presenta un desbordamiento de pila de 1 byte en `rt_copy_memory`, que escribió incondicionalmente un terminador nulo en `dst[len]`.
