Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host is missing security update KB4015549. It is,
therefore, affected by multiple 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 the
win32k component due to improper handling of kernel
information. A local attacker can exploit this, via a
specially crafted application, to disclose sensitive
information. (CVE-2017-0058)

- Multiple privilege escalation vulnerabilities exist 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
execute arbitrary code with elevated privileges.
(CVE-2017-0155, CVE-2017-0156)

- A flaw exists in the VBScript engine due to improper
handling of objects in memory. An unauthenticated,
remote attacker can exploit this, by convincing a user
to visit a malicious website or open a specially crafted
document file, to execute arbitrary code.
(CVE-2017-0158)

- 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)

- An information disclosure vulnerability exists in
Windows Hyper-V Network Switch due to improper validation
of user-supplied input. A guest attacker can exploit
this to disclose sensitive information on the host
server. (CVE-2017-0168)

- 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)

- A denial of service vulnerability exists 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 this, 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
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-2017-0202)

- 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)
