Descriptions

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.

curl y libcurl versiones 7.27.0 hasta 7.35.0, cuando se ejecuta en Windows y utiliza el backend TLS SChannel/Winssl, no comprueba que el nombre de host del servidor coincida con un nombre de dominio en el campo subject's Common Name (CN) o subjectAltName del certificado X.509 cuando se accede a una URL que usa una dirección IP numérica, que permite a los atacantes de tipo man-in-the-middle falsificar servidores por medio de un certificado válido arbitrario.

New curl packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues.
