"The version of Microsoft Edge installed on the remote Windows host is
missing Cumulative Security Update 3163656. It is, therefore, affected
by multiple vulnerabilities :

  - A security feature bypass vulnerability exists due to a
    failure to properly validate specially crafted
    documents. An unauthenticated, remote attacker can
    exploit this vulnerability by convincing a user to load
    a page or visit a website containing malicious content,
    allowing the attacker to bypass the Edge Content
    Security Policy (CSP). (CVE-2016-3198)

  - Multiple remote code execution vulnerabilities exist in
    the Chakra JavaScript engine due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these vulnerabilities by convincing a user
    to visit a specially crafted website or open a specially
    crafted Microsoft Office document that hosts the Edge
    rendering engine, resulting in the execution of
    arbitrary code in the context of the current user.
    (CVE-2016-3199, CVE-2016-3202, CVE-2016-3214,
    CVE-2016-3222)

  - Multiple information disclosure vulnerabilities exist
    due to improper parsing of .pdf files. An
    unauthenticated, remote attacker can exploit these
    vulnerabilities by convincing a user to open a specially
    crafted .pdf file, resulting in the disclosure of
    sensitive information in the context of the current
    user. (CVE-2016-3201, CVE-2016-3215)

  - A remote code execution vulnerability exists due to
    improper parsing of .pdf files. An unauthenticated,
    remote attacker can exploit this vulnerability by
    convincing a user to open a specially crafted .pdf file,
    resulting in the execution of arbitrary code in the
    context of the current user. (CVE-2016-3203)
