Created mupdf tracking bugs for this issue: Affects: fedora-all [bug 2255929]
None of those CVE links is accessible. As such, they provide no useful information.
OP does not seem to care about accessibility of CVE information, it seems. In any case, publicly searchable CVEs give no information about the actual bug nor how to reproduce it nor the analysis, and the analysis has not been redone by the CVE reporter for 6 mupdf versions now, nor for upstream's extensive work beyond the latest release. If cannot confirm validity I will have to close the bug against mupdf accordingly.
