The details of TROVE-2023-006 haven't been disclosed by the Tor Project to leave time for users to upgrade before revealing more. We only know that the Tor Project describes TROVE-2023-006 as a "remote triggerable assert on onion services".
Nuestro equipo cree que esta vulnerabilidad podría afectar a los usuarios de Tails que están creando servicios onion desde sus Tails, por ejemplo al compartir archivos o publicar un sitio web usando OnionShare.
This vulnerability might allow an attacker who already knows your OnionShare address to make your Tor client crash. A powerful attacker might be able to further exploit this crash to reveal your IP address.
This analysis is only a hypothesis because our team doesn't have access to more details about this vulnerability. Still, we are releasing this emergency release as a precaution.
OnionShare is the only application included in Tails that creates onion services. You are not affected by this vulnerability if you don't use OnionShare in Tails and only use Tails to connect to onion services and don't create onion services using Additional Software.
