The version of Windows running on the remote host is affected by multiple vulnerabilities :
Multiple information disclosure vulnerabilities exist due to the Win32k.sys kernel-mode driver improperly handling objects in memory. A local attacker can exploit this to reveal private address information during a function call, resulting in the disclosure of kernel memory contents. (CVE-2015-1676, CVE-2015-1677, CVE-2015-1678, CVE-2015-1679, CVE-2015-1680)
A privilege escalation vulnerability exists due to the Win32k.sys kernel-mode driver improperly handling objects in memory. A local attacker can exploit this flaw, via a specially crafted application, to execute arbitrary code in kernel mode. This vulnerability is reportedly being exploited in the wild. (CVE-2015-1701)
