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=high # testing, stable request=testing # Bug numbers: 1234,9876 bugs=2250329,2250331 # 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 FEDORA-2023-d2956318e4 has been submitted as an update to Fedora 39. https://bodhi.fedoraproject.org/updates/FEDORA-2023-d2956318e4 Regarding Fedora 37 and 38: Unfortunately, asyncssh 2.14.1 requires python3-cryptography >= 39 because it uses the unsafe_skip_rsa_key_validation argument: https://cryptography.io/en/latest/hazmat/primitives/asymmetric/rsa/#cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateNumbers.private_key https://asyncssh.readthedocs.io/en/latest/changes.html#release-2-14-0-30-sep-2023 I'm not sure if there is a good workaround. Sure, I'm not worried about f37, because it's EOL soon, anyways, but f38. We might patch 2.14.1 such that that argument is simply not passed along here: https://github.com/ronf/asyncssh/blob/e9e95aed50b10a54d5f69ca8bc055b40cc880ae8/asyncssh/crypto/rsa.py#L108 However, this would conflict with the upstream documentation and would make certain operations slower, cf.: https://github.com/ronf/asyncssh/commit/e70969f32257a9ee4002f5c33a91a6d2b34b18dc FEDORA-2023-d2956318e4 has been pushed to the Fedora 39 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2023-d2956318e4` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2023-d2956318e4 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. FEDORA-2023-d2956318e4 has been pushed to the Fedora 39 stable repository. If problem still persists, please make note of it in this bug report. FWIW, the build logs of the F37/F38 builds that fail due to too old python-cryptography, as described above: https://koji.fedoraproject.org/koji/taskinfo?taskID=109172662 https://koji.fedoraproject.org/koji/taskinfo?taskID=109173314 |
