The version of Microsoft Office installed on the remote Mac OS X host is affected by multiple vulnerabilities :
Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. A remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in execution of arbitrary code in the context of the current user. (CVE-2015-6038, CVE-2015-6094)
A spoofing vulnerability exists in Microsoft Outlook for Mac due to improper sanitization of HTML content. A remote attacker can exploit this, via a crafted email, to spoof content or to chain an attack to other vulnerabilities in web services. (CVE-2015-6123)
