issue in firmware update daemon library 'fwupd' as the return value of
gpgme_op_verify_result was not being checked.

For Debian 9 'Stretch', this issue has been fixed in fwupd version
0.7.4-2+deb9u1.

We recommend that you upgrade your fwupd packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
