We don't fix medium severity CVEs in RHEL 7 this late in the release cycle, so no fix in EPEL 7 either, unless somebody contributes it.
OK then, this just got serious :) Let me try reproducing it first: $ mock -r epel-7-x86_64 init ... $ mock -r epel-7-x86_64 install python34 ... Installed: python34.x86_64 0:3.4.10-8.el7 Dependency Installed: python34-libs.x86_64 0:3.4.10-8.el7 ... $ mock -r epel-7-x86_64 shell --unpriv ... <mock-chroot> sh-4.2$ python3.4 Python 3.4.10 (default, Jun 23 2021, 22:06:51) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import hashlib >>> h = hashlib.sha3_224() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute 'sha3_224' Seems like there is no such thing in here. https://docs.python.org/3.6/whatsnew/3.6.html says "The hashlib module received support for the BLAKE2, SHA-3 and SHAKE hash algorithms and the scrypt() key derivation function."

Thank you for checking this Miro! :)
