"The version of Windows running on the remote host is affected by the
following vulnerabilities :
- Information disclosure vulnerabilities exist in the
kernel-mode driver that can reveal portions of kernel
memory. An attacker can exploit these and gain
information about the system, which can then be used
to launch further attacks. (CVE-2015-0077,
CVE-2015-0094, CVE-2015-0095)
- A privilege escalation vulnerability exists in the
kernel-mode driver due to improper validation of thread
tokens. An authenticated attacker, using a specially
crafted application, can exploit this issue to gain
administrative credentials in order to elevate
privileges. (CVE-2015-0078)");
