Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host is missing security update KB4015551. It is,
therefore, affected by the following vulnerabilities :

- An information disclosure vulnerability exists in the
open-source libjpeg image processing library due to
improper handling of objects in memory. An
unauthenticated, remote attacker can exploit this to
disclose sensitive information that can be utilized to
bypass ASLR security protections. (CVE-2013-6629)

- An information disclosure vulnerability exists in
Windows DirectShow due to improper handling of objects
in memory. Any unauthenticated, remote attacker can
exploit this, by convincing a user to visit a website
with specially crafted media content, to disclose
sensitive information. (CVE-2017-0042)

- Multiple information disclosure vulnerabilities exist in
the win32k component due to improper handling of kernel
information. A local attacker can exploit these
vulnerabilities, via a specially crafted application, to
disclose sensitive information. (CVE-2017-0058,
CVE-2017-0188)

- Multiple flaws exist in Windows Hyper-V Network Switch
due to improper validation of input from the guest
operating system. A local attacker can exploit these,
via a specially crafted application on the guest, to
execute arbitrary code on the host system.
(CVE-2017-0163, CVE-2017-0180)

- A flaw exists in LDAP due to buffer request lengths not
being properly calculated. An unauthenticated, remote
attacker can exploit this, via specially crafted traffic
sent to a Domain Controller, to run processes with
elevated privileges. (CVE-2017-0166)

- Multiple information disclosure vulnerabilities exist in
Windows Hyper-V Network Switch due to improper validation
of user-supplied input. A guest attacker can exploit
these to disclose sensitive information on the host
server. (CVE-2017-0168, CVE-2017-0169)

- Multiple denial of service vulnerabilities exist in
Windows Hyper-V Network Switch due to improper
validation of input from the guest operating system. A
local attacker on the guest can exploit these
vulnerabilities, via a specially crafted application, to
crash the host system. (CVE-2017-0182, CVE-2017-0183,
CVE-2017-0185, CVE-2017-0186)

- Multiple denial of service vulnerabilities exist in
Hyper-V due to improper validation of input from a
privileged user on a guest operating system. A local
attacker on the guest can exploit these, via a specially
crafted application, to cause the host system to crash.
(CVE-2017-0184)

- A flaw exists in Windows due to improper handling of
objects in memory that allows an attacker to cause a
denial of service condition. (CVE-2017-0191)

- An information disclosure vulnerability exists in the
Adobe Type Manager Font Driver (ATMFD.dll) due to
improper handling of objects in memory. An
unauthenticated, remote attacker can exploit this, by
convincing a user to open a specially crafted document
or visit a malicious web page, to disclose sensitive
information. (CVE-2017-0192)

- An arbitrary code execution vulnerability exists in
Microsoft Office and Windows WordPad due to improper
handling of specially crafted files. An unauthenticated,
remote attacker can exploit this, by convincing a user
to open a malicious file, to execute arbitrary code in
the context of the current user. Note that this
vulnerability is being utilized to spread the Petya
ransomware. (CVE-2017-0199)

- A memory corruption issue exists in Internet
Explorer in the JScript and VBScript engines due to
improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this, by
convincing a user to visit a malicious website, to
execute arbitrary code. (CVE-2017-0201)

- A privilege escalation vulnerability exists in Internet
Explorer due to a failure to properly enforce
cross-domain policies. An unauthenticated, remote
attacker can exploit this to inject arbitrary content
and gain elevated privileges. (CVE-2017-0210)

- A privilege escalation vulnerability exists in Microsoft
Windows OLE due to an unspecified failure in
integrity-level checks. An authenticated, remote
attacker can exploit this to run an application with
limited privileges at a medium integrity level. Note
that this vulnerability by itself does not allow
arbitrary code execution but can be used in conjunction
other vulnerabilities. (CVE-2017-0211)
