KB4462915: Windows 7 and Windows Server 2008 R2 October 2018 Security Update

High Nessus Plugin ID 118001

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4462915
or cumulative update 4462923. It is, therefore, affected by
multiple vulnerabilities :

- 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-2018-8460,
CVE-2018-8491)

- A security feature bypass vulnerability exists in DNS
Global Blocklist feature. An attacker who successfully
exploited this vulnerability could redirect traffic to
malicious DNS endpoints. The update addresses the
vulnerability by updating DNS Server Role record
additions to not bypass the Global Query Blocklist.
(CVE-2018-8320)

- 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-2018-8330)

- A remote code execution vulnerability exists in the way
that Microsoft Graphics Components handle objects in
memory. An attacker who successfully exploited the
vulnerability could execute arbitrary code on a target
system. (CVE-2018-8432)

- An information disclosure vulnerability exists when
DirectX 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 DirectX handles objects in memory.
(CVE-2018-8486)

- An information disclosure vulnerability exists in the
way that the Windows Graphics Device Interface (GDI)
handles objects in memory, allowing an attacker to
retrieve information from a targeted system. By itself,
the information disclosure does not allow arbitrary code
execution; however, it could allow arbitrary code to be
run if the attacker uses it in combination with another
vulnerability. (CVE-2018-8472)

- 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-2018-8489)

- An elevation of privilege vulnerability exists when NTFS
improperly checks access. An attacker who successfully
exploited this vulnerability could run processes in an
elevated context. (CVE-2018-8411)

- 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-2018-8494)

- An information disclosure vulnerability exists when
Windows Media Player improperly discloses file
information. Successful exploitation of the
vulnerability could allow an attacker to determine the
presence of files on disk. (CVE-2018-8481,
CVE-2018-8482)

- A remote code execution vulnerability exists when
"Windows Theme API" does not properly
decompress files. An attacker who successfully exploited
the vulnerability could run arbitrary code in the
context of the current user. If the current user is
logged on with administrative user rights, an attacker
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.
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-2018-8413)

- 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. An attacker could then install programs;
view, change, or delete data; or create new accounts
with full user rights. (CVE-2018-8453)

- A remote code execution vulnerability exists in the
Microsoft JET Database Engine. 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-2018-8423)

- An Elevation of Privilege vulnerability exists in Filter
Manager when it improperly handles objects in memory. An
attacker who successfully exploited this vulnerability
could execute elevated code and 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-2018-8333)
