KB4457132: Windows 10 September 2018 Security Update

High Nessus Plugin ID 117414

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4457132.
It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in the way
the scripting engine handles 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-2018-8457)

- An information disclosure vulnerability exists when the
Windows GDI component improperly discloses the contents
of its memory. An attacker who successfully exploited
the vulnerability could obtain information to further
compromise the users system. There are multiple ways an
attacker could exploit the vulnerability, such as by
convincing a user to open a specially crafted document,
or by convincing a user to visit an untrusted webpage.
The security update addresses the vulnerability by
correcting how the Windows GDI component handles objects
in memory. (CVE-2018-8424)

- An elevation of privilege vulnerability exists in
Windows that allows a sandbox escape. An attacker who
successfully exploited the vulnerability could use the
sandbox escape to elevate privileges on an affected
system. This vulnerability by itself does not allow
arbitrary code execution. However, the vulnerability
could allow arbitrary code to run if an attacker uses it
in combination with another vulnerability, such as a
remote code execution vulnerability or another elevation
of privilege vulnerability, that can leverage the
elevated privileges when code execution is attempted.
The security update addresses the vulnerability by
correcting how Windows parses files. (CVE-2018-8468)

- A remote code execution vulnerability exists when
Windows does not properly handle specially crafted image
files. An attacker who successfully exploited the
vulnerability could execute arbitrary code.
(CVE-2018-8475)

- An elevation of privilege vulnerability exists when
Windows improperly handles calls to Advanced Local
Procedure Call (ALPC). An attacker who successfully
exploited this vulnerability could run arbitrary code in
the security context of the local system. An attacker
could then install programs; view, change, or delete
data; or create new accounts with full user rights.
(CVE-2018-8440)

- 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. The vulnerability by itself does
not allow arbitrary code to run. However, this
vulnerability could be used in conjunction with one or
more vulnerabilities (for example a remote code
execution vulnerability and another elevation of
privilege vulnerability) to take advantage of the
elevated privileges when running. The security update
addresses the vulnerability by modifying how Microsoft
Edge handles sandboxing. (CVE-2018-8469)

- An information disclosure vulnerability exists when the
Windows kernel improperly handles objects in memory. An
attacker who successfully exploited this vulnerability
could obtain information to further compromise the users
system. An authenticated attacker could exploit this
vulnerability by running a specially crafted
application. The update addresses the vulnerability by
correcting how the Windows kernel handles objects in
memory. (CVE-2018-8442, CVE-2018-8443)

- A remote code execution vulnerability exists when
Windows Hyper-V on a host server fails to properly
validate input from an authenticated user on a guest
operating system. (CVE-2018-8439)

- An elevation of privilege vulnerability exists when the
Windows Kernel API improperly handles registry objects
in memory. An attacker who successfully exploited the
vulnerability could gain elevated privileges on a
targeted system. A locally authenticated attacker could
exploit this vulnerability by running a specially
crafted application. The security update addresses the
vulnerability by helping to ensure that the Windows
Kernel API properly handles objects in memory.
(CVE-2018-8410)

- An elevation of privilege vulnerability exists when the
DirectX Graphics Kernel (DXGKRNL) driver improperly
handles objects in memory. An attacker who successfully
exploited this vulnerability could run processes in an
elevated context. (CVE-2018-8462)

- An information disclosure vulnerability exists when the
Windows kernel improperly handles objects in memory. An
attacker who successfully exploited this vulnerability
could obtain information to further compromise the users
system. (CVE-2018-8446)

- A remote code execution vulnerability exists in the way
that the Chakra scripting engine handles objects in
memory in Microsoft Edge. 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-2018-8367, CVE-2018-8466,
CVE-2018-8467)

- 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-2018-8438)

- An information disclosure vulnerability exists when
Windows Hyper-V on a host operating system fails to
properly validate input from an authenticated user on a
guest operating system. (CVE-2018-8434)

- A remote code execution vulnerability exists when the
Windows font library improperly handles specially
crafted embedded fonts. 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-2018-8332)

- An information disclosure vulnerability exists when the
browser scripting engine improperly handle object types.
An attacker who has successfully exploited this
vulnerability might be able to read privileged data
across trust boundaries. In browsing scenarios, an
attacker could convince a user to visit a malicious site
and leverage the vulnerability to obtain privileged
information from the browser process, such as sensitive
data from other opened tabs. An attacker could also
inject malicious code into advertising networks used by
trusted sites or embed malicious code on a compromised,
but trusted, site. The security update addresses the
vulnerability by correcting how the browser scripting
engine handles object types. (CVE-2018-8315)

- 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
control of an affected system. An attacker could then
install programs; view, change, or delete data; or
create new accounts with full user rights. Users whose
accounts are configured to have fewer user rights on the
system could be less impacted than users who operate
with administrative user rights. (CVE-2018-8392,
CVE-2018-8393)

- A denial of service vulnerability exists in the
Microsoft Server Block Message (SMB) when an attacker
sends specially crafted requests to the server. An
attacker who exploited this vulnerability could cause
the affected system to crash. To attempt to exploit this
issue, an attacker would need to send specially crafted
SMB requests to the target system. Note that the denial
of service vulnerability would not allow an attacker to
execute code or to elevate their user rights, but it
could cause the affected system to stop accepting
requests. The security update addresses the
vulnerability by correcting the manner in which SMB
handles specially crafted client requests.
(CVE-2018-8335)

- An information disclosure vulnerability exists in the
way that the Microsoft Server Message Block 2.0 (SMBv2)
server handles certain requests. An attacker who
successfully exploited this vulnerability could craft a
special packet, which could lead to information
disclosure from the server. (CVE-2018-8444)

- A remote code execution vulnerability exists when
Internet Explorer improperly accesses 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. An attacker who
successfully exploited the vulnerability could gain the
same user rights as the current user. (CVE-2018-8447)

- An information disclosure vulnerability exists in
Windows when the Windows bowser.sys kernel-mode driver
fails to properly handle objects in memory. An attacker
who successfully exploited the vulnerability could
potentially disclose contents of System memory.
(CVE-2018-8271)

- An information disclosure vulnerability exists when the
Windows kernel fails to properly initialize a memory
address. An attacker who successfully exploited this
vulnerability could obtain information to further
compromise the users system. (CVE-2018-8419)

- An remote code execution vulnerability exists when
Microsoft Edge PDF Reader improperly handles objects in
memory. The vulnerability could corrupt memory in such 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. If the current
user is logged on with administrative user rights, an
attacker could take control of an affected system. An
attacker could then install programs; view, change, or
delete data; or create new accounts with full user
rights. (CVE-2018-8464)

- A remote code execution vulnerability exists when
Microsoft .NET Framework processes input. An attacker
who successfully exploited this vulnerability could take
control of an affected system. (CVE-2018-8421)

- A remote code execution vulnerability exists when the
Microsoft XML Core Services MSXML parser processes user
input. An attacker who successfully exploited the
vulnerability could run malicious code remotely to take
control of the users system. (CVE-2018-8420)

- An information disclosure vulnerability exists when the
scripting engine does not properly handle objects in
memory in Microsoft browsers. An attacker who
successfully exploited the vulnerability could obtain
information to further compromise the users system.
(CVE-2018-8452)

- A security feature bypass exists when Device Guard
incorrectly validates an untrusted file. An attacker who
successfully exploited this vulnerability could make an
unsigned file appear to be signed. Because Device Guard
relies on the signature to determine the file is non-
malicious, Device Guard could then allow a malicious
file to execute. In an attack scenario, an attacker
could make an untrusted file appear to be a trusted
file. The update addresses the vulnerability by
correcting how Device Guard handles untrusted files.
(CVE-2018-8449)

- An information disclosure vulnerability exists when the
Windows Graphics component improperly handles objects in
memory. An attacker who successfully exploited this
vulnerability could obtain information to further
compromise the users system. An authenticated attacker
could exploit this vulnerability by running a specially
crafted application. The update addresses the
vulnerability by correcting how the Windows Graphics
Component handles objects in memory. (CVE-2018-8433)

- A security feature bypass vulnerability exists when
Windows Hyper-V BIOS loader fails to provide a high-
entropy source. (CVE-2018-8435)

- A remote code execution vulnerability exists in the way
that the scripting engine handles objects in memory in
Microsoft Edge. 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-2018-8354)

- A security feature bypass vulnerability exists in
Internet Explorer due to how scripts are handled that
allows a universal cross-site scripting (UXSS)
condition. An attacker could use the UXSS vulnerability
to access any session belonging to web pages currently
opened (or cached) by the browser at the time the attack
is triggered. (CVE-2018-8470)

- A spoofing vulnerability exists when Microsoft Edge
improperly handles specific HTML content. An attacker
who successfully exploited this vulnerability could
trick a user into believing that the user was on a
legitimate website. The specially crafted website could
either spoof content or serve as a pivot to chain an
attack with other vulnerabilities in web services.
(CVE-2018-8425)
