  - An information disclosure vulnerability exists due to

    vulnerability by convincing a user to open a file or
    visit a website containing a specially crafted OpenType
    font, resulting in the disclosure of sensitive
    information. (MS15-044 / CVE-2015-1670)

  - A remote code execution vulnerability exists due to
    improper handling of TrueType font files by the Windows
    DirectWrite library. A remote attacker can exploit this
    vulnerability by convincing a user to open a specially
    crafted document or visit a website containing a
    specially crafted TrueType font file, resulting in
    execution of arbitrary code in the context of the
    current user. (MS15-044 / CVE-2015-1671)

  - A flaw exists in Microsoft Silverlight that allows a
    remote attacker, via a specially crafted Silverlight
    application, to execute arbitrary code with the same or
    higher level of permissions as the currently logged on
    user. (MS15-049 / CVE-2015-1715)");
