Windows 2008 October 2017 Multiple Security Updates (KRACK)

Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host is missing multiple security updates released
on 2017/10/10. It is, therefore, affected by multiple
vulnerabilities :

- 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-2017-11771)

- An elevation of privilege vulnerability exists when the
Windows Graphics Component improperly handles objects in
memory. An attacker who successfully exploited this
vulnerability could run processes in an elevated
context. (CVE-2017-11824)

- An elevation of privilege vulnerability exists when the
Windows kernel-mode driver 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-2017-8689, CVE-2017-8694)

- 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-2017-8717,
CVE-2017-8718)

- 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-2017-11816)

- An information disclosure vulnerability exists in the
way that the Windows SMB Server handles certain
requests. An authenticated attacker who successfully
exploited this vulnerability could craft a special
packet, which could lead to information disclosure from
the server. (CVE-2017-11815)

- 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-2017-11765, CVE-2017-11814)

- A remote code execution vulnerability exists in the way
that the scripting engine handles objects in memory in
Internet Explorer. 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-2017-11793, CVE-2017-11810)

- A remote code execution vulnerability exists when the
Windows font library improperly handles specially
crafted embedded fonts. An attacker who successfully
exploited the 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-2017-11762,
CVE-2017-11763)

- An information disclosure vulnerability exists when
Internet Explorer improperly handles objects in memory.
An attacker who successfully exploited the vulnerability
could obtain information to further compromise the users
system. (CVE-2017-11790)

- An information disclosure vulnerability exists when the
Windows kernel improperly initializes objects in memory.
(CVE-2017-11817)

- 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-2017-11781)

- 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-2017-11822)

- An Information disclosure vulnerability exists when
Windows Search improperly handles objects in memory. An
attacker who successfully exploited the vulnerability
could obtain information to further compromise the users
system. (CVE-2017-11772)

- A remote code execution vulnerability exists in the way
that the Microsoft Server Message Block 1.0 (SMBv1)
server handles certain requests. An attacker who
successfully exploited the vulnerability could gain the
ability to execute code on the target server.
(CVE-2017-11780)

- An information disclosure vulnerability exists in the
Windows kernel that could allow an attacker to retrieve
information that could lead to a Kernel Address Space
Layout Randomization (ASLR) bypass. An attacker who
successfully exploited the vulnerability could retrieve
the memory address of a kernel object. (CVE-2017-11784,
CVE-2017-11785)

- A spoofing vulnerability exists in the Windows
implementation of wireless networking. An attacker who
successfully exploited this vulnerability could
potentially replay broadcast and/or multicast traffic
to hosts on a WPA or WPA 2-protected wireless network.
(CVE-2017-13080)
