The version of Microsoft Silverlight installed on the remote host is reportedly affected by several vulnerabilities :

  • Incorrect handling of TrueType font (TTF) files could lead to arbitrary code execution. (CVE-2011-3402 / CVE-2012-0159)

  • A double-free condition leading to arbitrary code execution could be triggered when rendering specially crafted XAML glyphs. (CVE-2012-0176)
