Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

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)
