Description Huzaifa S. Sidhpurwala 2016-06-06 00:17:17 EDT

Security researcher Toni Huttunen reported that once the favicon is requested from a site, the favicon network connection will persist even when the page is later closed. This allows a malicious site to continue to use this channel to send requests to the browser, leading to potential information disclosure, such as the IP address of the user.
