"The remote Windows host is affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the
    Windows kernel-mode driver due to improper handling of
    buffer elements. A local attacker can exploit this
    vulnerability to request the contents of specific memory
    addresses. (CVE-2015-1719)

  - An elevation of privilege vulnerability exists in the
    Windows kernel-mode driver due to a user-after-free
    error. A remote attacker can exploit this vulnerability
    by convincing a user to run a specially crafted
    application, resulting in the execution of arbitrary
    code in kernel mode. (CVE-2015-1720)

  - A elevation of privilege vulnerability exists in the
    Windows kernel-mode driver due to a NULL pointer
    dereference flaw. A remote attacker can exploit this
    vulnerability by convincing a user to run a specially
    crafted application, resulting in the execution of
    arbitrary code in kernel mode. (CVE-2015-1721)

  - Multiple elevation of privilege vulnerabilities exist in
    the Windows kernel-mode driver due to improper handling
    of objects in memory. A local attacker can exploit these
    vulnerabilities, with a specially crafted application,
    to escalate privileges to full administrative rights.
    (CVE-2015-1722, CVE-2015-1723, CVE-2015-1724,
    CVE-2015-1726)

  - Multiple elevation of privilege vulnerabilities exist in
    the Windows kernel-mode driver due to improperly
    validated user-supplied input. A local attacker can
    exploit these vulnerabilities, with a specially crafted
    application, to escalate privileges to full
    administrative rights. (CVE-2015-1725, CVE-2015-1727)

  - Multiple elevation of privilege vulnerabilities exist in
    the Windows kernel-mode driver due a failure to properly
    free memory. A local attacker can exploit these
    vulnerabilities, with a specially crafted application,
    to execute arbitrary code in the context of another
    user. (CVE-2015-1725, CVE-2015-1727)");
