the buffer out-of-bounds check in slice() does not take into account the possibility for arithmetic overflow. this commit fixes the oob check by adding an overflow check. it also refactors the slice check into a helper function, and adds relevant tests. patches GHSA-9x7f-gwxq-6f2c. --------- Co-authored-by: cyberthirst <[email protected]>
