TVs with Internet functionalities, which are commonly called Smart TVs, are gaining more and more popularity and can soon be found in every household. Some of these devices have integrated web browsers that enable consumers to browse the Internet.

These issues have been found on the E series (models from 2012) and F series (models from 2013) of the Samsung Smart TV devices. In April 2014 Samsung distributed a patch for these devices.
