Descriptions

WebCore/platform/network/soup/SocketStreamHandleImplSoup.cpp in the libsoup network backend of WebKit, as used in WebKitGTK+ prior to version 2.20.0 or without libsoup 2.62.0, unexpectedly failed to use system proxy settings for WebSocket connections. As a result, users could be deanonymized by crafted web sites via a WebSocket connection.

WebCore/platform/network/soup/SocketStreamHandleImplSoup.cpp en el backend de red de WebKit, tal y como se emplea en WebKitGTK+ en versiones anteriores a la 2.20.0 o sin libsoup 2.62.0, falló inesperadamente a la hora de emplear las opciones de proxy del sistema para las conexiones WebSocket. Como resultado, los usuarios pueden perder su anonimato mediante sitios web manipulados a los que se accede a través de una conexión WebSocket.
