Hola, va una mica tard, però per la gravetat ho envio igualment:
https://blog.torproject.org/tor-browser-75a7-released
/This release features an important security update to Tor Browser for
macOS and Linux users. Due to a //Firefox bug
<
https://bugzilla.mozilla.org/show_bug.cgi?id=1412081>//in handling
file:// URLs it is possible on both systems that users leak their IP
address. Once an affected user navigates to a specially crafted URL the
operating system may directly connect to the remote host, bypassing Tor
Browser. //*Tails users and users of our sandboxed-tor-browser are
unaffected, though*//./
Per evitar el forat, recordeu d'actualitzar el navegador de tor el
proper cop que l'obriu sisplau!
