"According to its self-reported version, the LibreOffice application running on the remote host is prior to 7.2.7 or 
7.3.2. It is, therefore, affected by an Improper Certificate Validation vulnerability where determining if a macro was 
signed by a trusted author was done by only matching the serial number and issuer string of the used certificate with 
that of a trusted certificate. 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 (CVE-2022-26305)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
