This is not sufficient to verify that the macro was actually signed with the certificate. An adversary could therefore create an arbitrary certificate with a serial number and an issuer string identical to a trusted certificate which LibreOffice would present as belonging to the trusted author, potentially leading to the user to execute arbitrary code contained in macros improperly trusted.
