The remote Windows host is running a version of Microsoft Office, Microsoft Word, Office Compatibility Pack, or Microsoft Word Viewer that is affected by the following remote code execution vulnerabilities :
A remote code execution vulnerability exists due to the way the XML parser used by Word resolves external entities. (CVE-2013-3160)
Remote code execution vulnerabilities exist due to memory corruption issues in the way that Microsoft Office parses files.
(CVE-2013-3847, CVE-2013-3848, CVE-2013-3849, CVE-2013-3850, CVE-2013-3851, CVE-2013-3852, CVE-2013-3853, CVE-2013-3854, CVE-2013-3855, CVE-2013-3856, CVE-2013-3857, CVE-2013-3858)
If an attacker can trick a user on the affected host into opening a specially crafted file, it may be possible to leverage these issues to read arbitrary files on the target system or execute arbitrary code, subject to the userβs privileges.
