The version of Microsoft Edge installed on the remote Windows host is
missing Cumulative Security Update 3177358. It is, therefore, affected
by multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist due
to a failure to properly access objects in memory. A
remote attacker can exploit these vulnerabilities by
convincing a user to visit a specially crafted website,
resulting in the execution of arbitrary code in the
context of the current user. (CVE-2016-3289,
CVE-2016-3293, CVE-2016-3319, CVE-2016-3322)

- A remote code execution vulnerability exists in the
Chakra JavaScript engine due to improper handling of
objects in memory. A remote attacker can exploit this
vulnerability by convincing a user to visit a specially
crafted website or open a specially crafted Office
document, resulting in the execution of arbitrary code
in the context of the current user. (CVE-2016-3296)

- Multiple information disclosure vulnerabilities exist
due to improper handling of objects in memory. A remote
attacker can exploit these vulnerabilities by convincing
a user to visit a specially crafted website, resulting
in the disclosure of sensitive information.
(CVE-2016-3326, CVE-2016-3327)

- An information disclosure vulnerability exists due to
improper handling of page content. A remote attacker can
exploit this vulnerability by convincing a user to visit
a specially crafted website, resulting in the disclosure
of specific files on a user's system. (CVE-2016-3329)
