Title: Microsoft Windows CryptoAPI欺骗漏洞

Description:

Microsoft Windows是美国微软公司发布的视窗操作系统。Microsoft CryptoAPI 是微软提供给开发人员的 Windows 安全服务应用程序接口，可用于加密的应用程序，实现数据加密、解密、签名及验证等功能。

Microsoft Windows CryptoAPI存在欺骗漏洞。该漏洞位于Windows CryptoAPI(Crypt32.dll)验证椭圆曲线加密算法证书的方式，可能影响信任的一些实例包括（不限于）：HTTPS连接、文件签名和电子邮件签名、以用户模式启动的签名可执行程序。攻击者可以利用该漏洞伪造代码签名证书对恶意可执行文件进行签名，从而使该文件看似来自受信任的合法来源。还可能滥用crypt32.dll中的漏洞来欺骗与特定软件相关的数字签名。
