Cumulative Security Update 3155538. It is, therefore, affected by
multiple vulnerabilities :

  - 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 this, by convincing a user to visit a
    crafted website or open a crafted document, to corrupt
    memory, resulting in the execution of arbitrary code in
    the context of the current user. (CVE-2016-0186,
