Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host is missing security update 4034674.
It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists when Microsoft
Windows improperly handles NetBIOS packets. An attacker
who successfully exploited this vulnerability could
cause a target computer to become completely
unresponsive. (CVE-2017-0174)

- A buffer overflow vulnerability exists in the Microsoft
JET Database Engine that could allow remote code
execution on an affected system. An attacker who
successfully exploited this vulnerability could take
complete control of an affected system. (CVE-2017-0250)

- A remote code execution vulnerability exists when
Microsoft Windows PDF Library improperly handles objects
in memory. The vulnerability could corrupt memory in a
way that enables an attacker to execute arbitrary code
in the context of the current user. An attacker who
successfully exploited the vulnerability could gain the
same user rights as the current user.
(CVE-2017-0293)

- An elevation of privilege vulnerability exists in
Microsoft Edge that could allow an attacker to escape
from the AppContainer sandbox in the browser. An
attacker who successfully exploited this vulnerability
could gain elevated privileges and break out of the Edge
AppContainer sandbox. (CVE-2017-8503)

- A remote code execution vulnerability exists in Windows
Input Method Editor (IME) when IME improperly handles
parameters in a method of a DCOM class. The DCOM server
is a Windows component installed regardless of which
languages/IMEs are enabled. An attacker can instantiate
the DCOM class and exploit the system even if IME is not
enabled. (CVE-2017-8591)

- An elevation of privilege vulnerability exists in
Windows when the Win32k component fails to properly
handle objects in memory. An attacker who successfully
exploited this vulnerability could run arbitrary code in
kernel mode. (CVE-2017-8593)

- A remote code execution vulnerability exists when
Windows Search handles objects in memory. An attacker
who successfully exploited this vulnerability could take
control of the affected system. An attacker could then
install programs; view, change, or delete data; or
create new accounts with full user rights.
(CVE-2017-8620)

- An elevation of privilege vulnerability exists in the
way that the Windows Subsystem for Linux handles NT
pipes. An attacker who successfully exploited the
vulnerability could execute code with elevated
permissions. (CVE-2017-8622)

- A denial of service vulnerability exists when Microsoft
Hyper-V Network Switch on a host server fails to
properly validate input from a privileged user on a
guest operating system. An attacker who successfully
exploited the vulnerability could cause the host server
to crash. (CVE-2017-8623)

- An elevation of privilege vulnerability exists when the
Windows Common Log File System (CLFS) driver improperly
handles objects in memory. (CVE-2017-8624)

- A denial of service vulnerability exists when Windows
Subsystem for Linux improperly handles objects in
memory. An attacker who successfully exploited this
vulnerability could cause a denial of service against
the local system.A attacker could exploit this
vulnerability by running a specially crafted
application.The update addresses the vulnerability by
correcting how Windows Subsystem for Linux handles
objects in memory. (CVE-2017-8627)

- This security update resolves a vulnerability in Windows
Error Reporting (WER). The vulnerability could allow
elevation of privilege if successfully exploited by an
attacker. An attacker who successfully exploited this
vulnerability could gain greater access to sensitive
information and system functionality. This update
corrects the way the WER handles and executes files.
(CVE-2017-8633)

- A remote code execution vulnerability exists in the way
that Microsoft browser JavaScript engines render content
when handling objects in memory. The vulnerability could
corrupt memory in such a way that an attacker could
execute arbitrary code in the context of the current
user. (CVE-2017-8634)

- A remote code execution vulnerability exists in the way
JavaScript engines render when handling objects in
memory in Microsoft browsers. The vulnerability could
corrupt memory in such a way that an attacker could
execute arbitrary code in the context of the current
user. An attacker who successfully exploited the
vulnerability could gain the same user rights as the
current user. (CVE-2017-8635)

- A remote code execution vulnerability exists in the way
that Microsoft browser JavaScript engines render content
when handling objects in memory. The vulnerability could
corrupt memory in such a way that an attacker could
execute arbitrary code in the context of the current
user. (CVE-2017-8636)

- A security feature bypass vulnerability exists in
Microsoft Edge as a result of how memory is accessed in
code compiled by the Edge Just-In-Time (JIT) compiler
that allows Arbitrary Code Guard (ACG) to be bypassed.
(CVE-2017-8637)

- A remote code execution vulnerability exists in the way
that Microsoft browser JavaScript engines render content
when handling objects in memory. The vulnerability could
corrupt memory in such a way that an attacker could

that Microsoft browser JavaScript engines render content
when handling objects in memory. The vulnerability could
corrupt memory in such a way that an attacker could
execute arbitrary code in the context of the current
user. (CVE-2017-8640)

- A remote code execution vulnerability exists in the way
JavaScript engines render when handling objects in
memory in Microsoft browsers. The vulnerability could
corrupt memory in such a way that an attacker could
execute arbitrary code in the context of the current
user. An attacker who successfully exploited the
vulnerability could gain the same user rights as the
current user. (CVE-2017-8641)

- An elevation of privilege vulnerability exists when
Microsoft Edge does not properly validate JavaScript
under specific conditions, potentially allowing script
to run with elevated privileges. (CVE-2017-8642)

attacker who successfully exploited the vulnerability
could obtain information to further compromise the users
system. (CVE-2017-8644)
