Why was this reported for cura?

Comment 4 Miro Hrončok 2023-08-22 09:35:59 UTC

Why was this reported for cura?

Comment 5 Vipul Nair 2023-08-22 11:14:33 UTC

we use griffon and depcli in order to fill affects,both tools show cura as affected.

Comment 6 Miro Hrončok 2023-08-22 11:24:15 UTC

I have never heard of griffon or depcli. Could you please tell me, how exactly is cura affected by a CVE in python-cryptography?

Comment 7 Vipul Nair 2023-08-22 11:43:24 UTC

griffon and depcli along with component registry are tools we use to fill trackers,of course we do not know every dependency and their dependancy in every product redhat ships.Here is the command i supplied depcli -v cryptography -e pypi 

component registry tells us 

fedora-37	cura	(cryptography.8, pypi)

hence the tracker.

Comment 8 Miro Hrončok 2023-08-22 13:03:30 UTC

I've scanned cura source in Fedora 37 for the affected code from https://github.com/pyca/cryptography/pull/9208/files and found nothing.

In fact, I don't think there are any bits of python-cryptography in cura other than:


requirements.txt
cryptography==3.4.8


Which does not affect the Fedora RPM package in any way.
