Comment 2 Benjamin Gilbert 2023-03-17 09:10:56 UTC
Ignition in Fedora 37 and Fedora 38 are not affected.  Ignition in Fedora 36 and 39 are affected, but by the nature of Ignition, malicious HTTP servers can generally already execute arbitrary code on the client, so a potential DoS is a low-severity issue.  Fedora 39 will pick up a fix on the next Ignition build.
