## Description

Tor Browser through 8.5.3 has an information exposure vulnerability. It
allows remote attackers to detect the browser's language via vectors
involving an IFRAME element, because text in that language is included in
the title attribute of a LINK element for a non-HTML page. This is related
to a behavior of Firefox before 68.
