危険度: : 高
CVE識別番号: CVE-2015-1637
概要
This security update resolves a vulnerability in Microsoft Windows that facilitates exploitation of the publicly disclosed FREAK technique, an industry-wide issue that is not specific to Windows operating systems. The vulnerability could allow a man-in-the-middle (MiTM) attacker to force the downgrading of the key length of an RSA key to EXPORT-grade length in a TLS connection. Any Windows system using Schannel to connect to a remote TLS server with an insecure cipher suite is affected.
