Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows 10 Version 1507 host is missing security update
KB4015221. 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 these
vulnerabilities, via a specially crafted application, to
disclose sensitive information. (CVE-2017-0058)

- A privilege escalation 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 execute
arbitrary code with elevated privileges. (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)

- A privilege escalation vulnerability exists in the
Microsoft .NET framework due to improper validation of
input when loading libraries. A local attacker can
exploit this to gain elevated privileges.
(CVE-2017-0160)

- 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-2017-0162, CVE-2017-0163)

- A privilege escalation vulnerability exists due to
improper sanitization of handles stored in memory. A
local attacker can exploit this to gain elevated
privileges. (CVE-2017-0165)

- 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)

- A flaw 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
disclose sensitive information. (CVE-2017-0167)
