Description

The remote Mac OS X host is running a version of Microsoft Excel that is affected by several vulnerabilities.

If an attacker can trick a user on the affected host into opening a specially crafted Excel file, these issues could be leveraged to execute arbitrary code subject to the user's privileges.
