A PGP signature bypass flaw was found in fwupd (all versions), which could
lead to the installation of unsigned firmware. As per upstream, a signature
bypass is theoretically possible, but not practical because the Linux
Vendor Firmware Service (LVFS) is either not implemented or enabled in
versions of fwupd shipped with Red Hat Enterprise Linux 7 and 8. The
highest threat from this vulnerability is to confidentiality and integrity.
