The upstream fix looks good and squashfs-tools-4.5-2 has the patch and is
in today's rawhide compose.
There will be a minor point release for squashfs-tools in the near future
with the fix. But phillip is waiting a short bit to see if any other
problems get discovered before making a new release.
There was one minor security issue noted in the release notes, so I will
be looking at getting this into f34 and f35 eventually. The issue is
with unsquashing untrusted squashfs images potentially writing files in
unexpected locations, so I think we can wait a short bit to see if there
are issues with the new version before getting it into f34 and f33.
