The remote Windows host is affected by several vulnerabilities in the Kernel-Mode drivers that could allow elevation of privilege :
Flaws in the way the Windows kernel-mode drivers manage driver objects could be exploited to execute arbitrary code in kernel mode. (CVE-2012-1864, CVE-2012-1865, CVE-2012-1866)
Windows kernel-mode drivers do not properly allocate memory when handling fonts, which could be exploited to execute arbitrary code in kernel mode. (CVE-2012-1867)
A race condition exists in the way that the kernel deals with specific thread creation attempts. This could be exploited to execute arbitrary code in kernel mode.
