The version of Microsoft Silverlight installed on the remote host is affected by multiple vulnerabilities :
An information disclosure vulnerability exists due to improper handling of OpenType fonts by the Windows DirectWrite library. A remote attacker can exploit this 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)
