Microsoft Office Unsupported Version Detection (Mac OS X)
Critical Nessus Plugin ID 91857
The remote host contains an unsupported version of Microsoft Office.
According to its version, the installation of Microsoft Office on the remote Mac OS X host is no longer supported. Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.
Upgrade to a version of Microsoft Office that is currently supported.
