The host is missing an important security update according to Microsoft security bulletin, MS11-077. The update is required to fix remote code execution vulnerabilities. The flaws are present in Microsoft Windows, which fails to handle a specially crafted font file (such as a .fon file) in a network share, a UNC or WebDAV location, or an e-mail attachment. Successful exploitation could allow an attacker to visit an untrusted remote file system location or WebDAV share and open the specially crafted font file, or open the file as an e-mail attachment.
