CVE-2014-2522 Information

Description

curl and libcurl 7.27.0 through 7.35.0 when running on Windows and using the SChannel/Winssl TLS backend does not verify that the server hostname matches a domain name in the subject’s Common Name (CN) or subjectAltName field of the X.509 certificate when accessing a URL that uses a numerical IP address which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate.
