The remote Windows host is running a version of the Windows kernel that is affected by the following vulnerabilities :

- A reference count leak, which could result in arbitrary code execution in the kernel. (CVE-2010-2549)

- Kernel-mode drivers load unspecified keyboard layers improperly, which could result in arbitrary code execution in the kernel. (CVE-2010-2743)

- Kernel-mode drivers do not properly validate unspecified window class data, which could result in arbitrary code execution in the kernel. (CVE-2010-2744)

Solution

Microsoft has released a set of patches for Windows 2003, XP, Vista, 2008, 7, and 2008 R2.
