Use the following template to for the 'fedpkg update' request to submit an update for this issue as it contains the top-level parent bug(s) as well as this tracking bug. This will ensure that all associated bugs get updated when new packages are pushed to stable. ===== # bugfix, security, enhancement, newpackage (required) type=security # low, medium, high, urgent (required) severity=medium # testing, stable request=testing # Bug numbers: 1234,9876 bugs=2140200,2141754 # Description of your update notes=Security fix for [PUT CVEs HERE] # Enable request automation based on the stable/unstable karma thresholds autokarma=True stable_karma=3 unstable_karma=-3 # Automatically close bugs when this marked as stable close_bugs=True # Suggest that users restart after update suggest_reboot=False ====== Additionally, you may opt to use the bodhi web interface to submit updates: https://bodhi.fedoraproject.org/updates/new 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." [fedora-scm]$ fedpkg clone python34 Cloning into 'python34'... [fedora-scm]$ cd python34 [python34 (rawhide)]$ git switch epel7 branch 'epel7' set up to track 'origin/epel7'. Switched to a new branch 'epel7' [python34 (epel7)]$ fedpkg --release rawhide prep ... [python34 (epel7 %)]$ cd Python-3.4.10/ [Python-3.4.10 (epel7 %)]$ rg -F 'rateInBytes' [Python-3.4.10 (epel7 %)]$ echo $? 1 Hence, Python 3.4 is not affected. Thank you for checking this Miro! :) |
