Descriptions

WKWebView in WebKit in Apple iOS before 10, iTunes before 12.5.1 on Windows, and Safari before 10 does not properly verify X.509 certificates from HTTPS servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

WKWebView en WebKit en Apple iOS en versiones anteriores a 10, iTunes en versiones anteriores a 12.5.1 en Windows y Safari en versiones anteriores a 10 no verifica correctamente certificados X.509 desde servidores HTTPS, lo que permite a atacantes man-in-the-middle suplantar servidores y obtener información sensible a través de un certificado manipulado.

Safari 10 is now available and addresses cross site scripting, code execution, and various other vulnerabilities.
