Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows Server 2012 host is missing either the KB4025331 or
KB4025343 security updates. It is, therefore, affected by the
following vulnerabilities :

- An information disclosure vulnerability exists in the
Windows Performance Monitor Console due to improper
parsing of XML input that contains a reference to an
external entity. An unauthenticated, remote attacker
can exploit this, by convincing a user to create a
Data Collector Set and import a specially crafted XML
file, to disclose arbitrary files via an XML external
entity (XXE) declaration. (CVE-2017-0170)

- A remote code execution vulnerability exists in Windows
Explorer due to improper handling of executable files
and shares during rename operations. An unauthenticated,
remote attacker can exploit this, by convincing a user
to open a specially crafted file, to execute arbitrary
code in the context of the current user. (CVE-2017-8463)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8467)

- An information disclosure vulnerability exists in Win32k
due to improper handling of objects in memory. A local
attacker can exploit this, via a specially crafted
application, to disclose sensitive information.
(CVE-2017-8486)

- A security bypass vulnerability exists in Microsoft
Windows when handling Kerberos ticket exchanges due to a
failure to prevent tampering with the SNAME field. A
man-in-the-middle attacker can exploit this to bypass
the Extended Protection for Authentication security
feature. (CVE-2017-8495)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8556)

- An information disclosure vulnerability exists in the
Windows System Information Console due to improper
parsing of XML input that contains a reference to an
external entity. An unauthenticated, remote attacker
can exploit this, by convincing a user to open a
specially crafted file, to disclose arbitrary files via
an XML external entity (XXE) declaration.
(CVE-2017-8557)

- An elevation of privilege vulnerability exists in the
Windows kernel due to improper handling of objects in
memory. A local attacker can exploit this, via a
specially crafted application, to execute arbitrary code
with elevated permissions. (CVE-2017-8561)

- An elevation of privilege vulnerability exists in the
Windows due to improper handling of calls to Advanced
Local Procedure Call (ALPC). An authenticated, remote
attacker can exploit this via a specially crafted
application, to run processes in an elevated context.
(CVE-2017-8562)

- An elevation of privilege vulnerability exists in
Windows due to Kerberos falling back to NT LAN Manager
(NTLM) Authentication Protocol as the default
authentication protocol. An authenticated, remote
attacker can exploit this, via an application that
sends specially crafted traffic to a domain controller,
to run processes in an elevated context. (CVE-2017-8563)

- An information disclosure vulnerability exists in the
Windows kernel due to improper initialization of objects
in memory. An authenticated, remote attacker can exploit
this, via a specially crafted application, to bypass
Kernel Address Space Layout Randomization (KASLR) and
disclose the base address of the kernel driver.
(CVE-2017-8564)

- A remote code execution vulnerability exists in
PowerShell when handling a PSObject that wraps a CIM
instance. An authenticated, remote attacker can exploit
this, via a specially crafted script, to execute
arbitrary code in a PowerShell remote session.
(CVE-2017-8565)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8573)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics Component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8577)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8578)

- An elevation of privilege vulnerability exists in the
Microsoft Graphics Component due to improper handling
of objects in memory. A local attacker can exploit this,
via a specially crafted application, to run arbitrary
code in kernel mode. (CVE-2017-8580)

- An elevation of privilege vulnerability exists in
Windows due to improper handling of objects in memory. A
local attacker can exploit this, via a specially crafted
application, to run arbitrary code in kernel mode.
(CVE-2017-8581)

- An information disclosure vulnerability exists in the
HTTP.sys server application component due to improper
handling of objects in memory. An unauthenticated,
remote attacker can exploit this, via a specially
crafted request, to disclose sensitive information.
(CVE-2017-8582)

- A denial of service vulnerability exists in Windows
Explorer that is triggered when Explorer attempts to
open a non-existent file. An unauthenticated, remote
attacker can exploit this, by convincing a user to visit
a specially crafted website, to cause a user's system to
stop responding. (CVE-2017-8587)

- A remote code execution vulnerability exists in WordPad
due to improper parsing of specially crafted files. An
unauthenticated, remote attacker can exploit this, by
convincing a user to open a specially crafted file, to
execute arbitrary code in the context of the current
user. (CVE-2017-8588)

- A remote code execution vulnerability exists in the
Windows Search component due to improper handling of
objects in memory. An unauthenticated, remote attacker
can exploit this, by sending specially crafted messages
to the Windows Search service, to elevate privileges and
execute arbitrary code. (CVE-2017-8589)

- An elevation of privilege vulnerability exists in the
Windows Common Log File System (CLFS) driver due to
improper handling of objects in memory. A local attacker
can exploit this, via a specially crafted application,
to run processes in an elevated context. (CVE-2017-8590)

- A security bypass vulnerability exists in Microsoft
browsers due to improper handling of redirect requests.
An unauthenticated, remote attacker can exploit this, by
convincing a user to visit a specially crafted website,
to bypass CORS redirect restrictions. (CVE-2017-8592)

- A remote code execution vulnerability exists in
Microsoft browsers in the JavaScript engines due to
improper handling of objects in memory. An
unauthenticated, remote attacker can exploit this, by
convincing a user to visit a specially crafted website,
to execute arbitrary code in the context of the current
user. (CVE-2017-8606)

- A remote code execution vulnerability exists in
Microsoft browsers in the JavaScript engines due to
improper handling of objects in memory. An
unauthenticated, remote attacker can exploit this, by
convincing a user to visit a specially crafted website,
to execute arbitrary code in the context of the current
user. (CVE-2017-8607)

- A remote code execution vulnerability exists in
Microsoft browsers in the JavaScript engines due to
improper handling of objects in memory. An
unauthenticated, remote attacker can exploit this, by
convincing a user to visit a specially crafted website,
to execute arbitrary code in the context of the current
user. (CVE-2017-8608)

- A remote code execution vulnerability exists in
Microsoft Edge in the scripting engine due to improper
handling of objects in memory. An unauthenticated,
remote attacker can exploit this, by convincing a user
to visit a specially crafted website, to execute
arbitrary code in the context of the current user.
(CVE-2017-8610)
