SynopsisThe remote Windows host is affected by multiple vulnerabilities.
DescriptionThe remote Windows host has a version of Microsoft Office, Office Compatibility Pack, Office Web Apps, Microsoft SharePoint, Microsoft Word, or Word Viewer installed that is affected by multiple vulnerabilities :
- Multiple remote code execution vulnerabilities exist in Microsoft Office software due to improper handling of objects in memory. An attacker can exploit these, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user. (CVE-2016-0021, CVE-2016-0134)
- A security feature bypass vulnerability exists in Microsoft Office software due to an improperly signed binary file. An attacker with write access to the target host can exploit this, by overwriting the file with a malicious binary with a similar configuration, to execute arbitrary code. (CVE-2016-0057).
