Bug Description

pysha3, pypy3, python3.X are affected by CVE-2022-37454, a security issue in Keccak
https://mouha.be/sha-3-buffer-overflow/

See: https://github.com/python/cpython/issues/98517

Testing:

python3.X/pypy3:

import hashlib; h = hashlib.sha3_224(); h.update(b'\x01'); \
h.update(b'\x01'*0xffff_ffff); \
assert h.hexdigest() == '80762e8ce6700f114fec0f621fd97c4b9c00147fa052215294cceeed'

pysha3:

import sha3; h = sha3.sha3_224(); h.update(b'\x01'); \
h.update(b'\x01'*0xffff_ffff); \
assert h.hexdigest() == '80762e8ce6700f114fec0f621fd97c4b9c00147fa052215294cceeed'

For pypy3 and pysha3, I have:
1. Verified the issues exist in the current packages, with the above tests.
2. Built the packages with the attached patches
3. Verified that the packages upgrade
4. Verified the security issues are resolved, with the above tests.

Hey Stefano, thanks for preparing the debdiffs for pypy3 and pysha3, my initial examination of them looks good. I'll work on sponsoring them.

For lunar, the fixed version of pypy3 is in lunar-proposed, so I've marked that as fixed committed.
