Fixed a buffer overrun issue #56

Closed smetz84 closed 2 years ago

smetz84 commented 3 years ago

There is a buffer overrun when sourcelen is a multiple of 8 (64 bits) or 4 (32 bits)

synopse commented 2 years ago

There is no buffer overflow here: look at the code and its comments and documentation. It may read some bytes after the source, but is very unlikely to trigger any GPF due to natural padding of the MM.
