Descriptions

GSocketClient in GNOME GLib through 2.62.4 may occasionally connect directly to a target address instead of connecting via a proxy server when configured to do so, because the proxy_addr field is mishandled. This bug is timing-dependent and may occur only sporadically depending on network delays. The greatest security relevance is in use cases where a proxy is used to help with privacy/anonymity, even though there is no technical barrier to a direct connection. NOTE: versions before 2.60 are unaffected.

GSocketClient en GNOME GLib versiones hasta 2.62.4, ocasionalmente puede conectarse directamente a una dirección de destino en lugar de conectarse por medio de un servidor proxy cuando se configuró para hacerlo, porque el campo proxy_addr es manejado inapropiadamente. Este error depende de la sincronización y puede ocurrir solo esporádicamente dependiendo de los retrasos de la red. La mayor relevancia de seguridad se encuentra en los casos de uso donde es utilizado un proxy para ayudar con la privacidad y el anonimato, aunque no existe una barrera técnica para una conexión directa. NOTA: las versiones anteriores a 2.60 no están afectadas.
