affected by multiple vulnerabilities :

  - A failure of the Windows kernel to properly validate
    changes in certain kernel objects allows a local user
    to run arbitrary code in kernel mode. (CVE-2009-1123)

  - Insufficient validation of certain pointers passed from
    user mode allows a local user to run arbitrary code in
    kernel mode. (CVE-2009-1124)

  - A failure to properly validate an argument passed to a
    Windows kernel system call allows a local user to run
    arbitrary code in kernel mode. (CVE-2009-1125)

  - Improper validation of input passed from user mode to
    the kernel when editing a specific desktop parameter
    allows a local user to run arbitrary code in kernel
    mode. (CVE-2009-1126)");
