MS13-087：Silverlight の脆弱性により、情報漏えいが起こる (2890788)
2013年10月9日
危険度: : 高
CVE識別番号: CVE-2013-3896
概要
This security update resolves a privately reported vulnerability in Microsoft Silverlight. The vulnerability could allow information disclosure if an attacker hosts a website that contains a specially crafted Silverlight application that is designed to exploit this vulnerability and then convinces a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements.�
Such websites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit a website. Instead, an attacker would have to convince users to visit a website, typically by getting them to click a link in an email message or in an Instant Messenger message that takes them to the attacker's website. It could also be possible to display specially crafted web content by using banner advertisements or by using other methods to deliver web content to affected systems.
