Signature Verification Bypass

libfwupd.so is vulnerable to signature verification bypass. It does not validate the return value from the function gpgmeopverify when PGP signature is verified, causing a FuKeyringResult return with no timestamp and an empty authority that subsequently allows an installation of unsigned firmware...
