It is, therefore, affected by multiple vulnerabilities :

  - A race condition that could lead to a remote code
    execution vulnerability exists in NetBT Session Services
    when NetBT fails to maintain certain sequencing
    requirements. (CVE-2017-0161)

  - A vulnerability exists when Microsoft Edge 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. (CVE-2017-11766)

  - A spoofing vulnerability exists in Microsoft's
    implementation of the Bluetooth stack. An attacker who
    successfully exploited this vulnerability could perform
    a man-in-the-middle attack and force a user's computer
    to unknowingly route traffic through the attacker's
    computer. The attacker can then monitor and read the
    traffic before sending it on to the intended recipient.
    (CVE-2017-8628)

  - An information disclosure vulnerability exists when
    Microsoft Edge improperly handles clipboard events. For
    an attack to be successful, an attacker must persuade a

    during clipboard activities. The update addresses the
    vulnerability by changing how Microsoft Edge handles
    clipboard events in the browser. (CVE-2017-8643)

  - An elevation of privilege vulnerability exists in
    Windows 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. To exploit
    this vulnerability, an attacker would first have to log
    on to the system. An attacker could then run a specially
    crafted application that could exploit the vulnerability
    and take control of an affected system. The update
    addresses this vulnerability by correcting how the
    Windows kernel-mode driver handles objects in memory.
    (CVE-2017-8675)

  - An information disclosure vulnerability exists in the
    way that the Windows Graphics Device Interface (GDI)
