# [Tails 5.19.1](https://tails.boum.org/news/version_5.19.1/index.en.html)
This release is an emergency release to fix an important security vulnerability in Tor. # Changes and updates * Update the _Tor_ client to 0.4.8.9, which fixes the TROVE-2023-006 vulnerability. 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_](https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/TROVE)". Our team thinks that this vulnerability could affect Tails users who are creating onion services from their Tails, for example when sharing files or publishing a website using _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. More details about TROVE-2023-006 will be available on the [Tor issue #40883](https://gitlab.torproject.org/tpo/core/tor/-/issues/40883) sometime after the release. # Fixed problems For more details, read our [changelog](https://gitlab.tails.boum.org/tails/tails/-/blob/master/debian/changelog). # Known issues None specific to this release.
