## Bugs
##
- Fixed buffer overflow in Stargazer Stellar Wallet XLM module in hash_encode() if a hash was cracked
- Fixed autotune unitialized tmps variable for slow hashes by calling _init kernel before calling _loop kernel
- Fixed datatype in function sha384_hmac_init_vector_128() that could come into effect if vector datatype was manually set
- Fixed false negative in all VeraCrypt hash-modes if both conditions are met: 1. use CPU for cracking and 2. PIM range was used
- Fixed out-of-boundary read in input_tokenizer() if the signature in the hash is longer than the length of the plugins' signature constant
- Fixed out-of-boundary read in Stuffit5 module in hash_decode()
