Doc Text: |
An Improper Certificate Validation vulnerability was found in LibreOffice, where determining if a trusted author signed a macro 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. This flaw allows an adversary to 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 executing arbitrary code contained in the improperly trusted macros.
