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

  - A race condition when creating certain types of kernel
    threads may allow a local attacker to execute arbitrary
    code in kernel mode and take complete control of the
    affected system. (CVE-2010-1888)

  - A double free vulnerability when the kernel initializes
    objects while handling certain errors may allow a local
    attacker to execute arbitrary code in kernel mode and
    take complete control of the affected system.
    (CVE-2010-1889)

  - A failure to properly validate access control lists on
    kernel objects may allow a local attacker to cause the
    system to become unresponsive and automatically
    restart. (CVE-2010-1890)");
