The Keccak XKCP SHA-3 reference implementation before fdc6fef has an
integer overflow and resultant buffer overflow that allows attackers to
execute arbitrary code or eliminate expected cryptographic properties.
This occurs in the sponge function interface.
Python 3.11 and later switched to using tiny_sha3 in GH-32060, so they
should not be affected.
