New Release: Tails 5.10

by tails | February 16, 2023

Changes and updates

Fixed problems

  • Avoid crashing when the download of an upgrade is stopped and resumed. (#18435)

  • Solve a possible privilege escalation through a symlink attack. (#19424)

    Dennis's Brinkrolf discovered that an adversary who could already run arbitrary code as the amnesia user in Tails 5.9, could have escalated their privileges to reading arbitrary files on the system. It might have been possible to use this as part of an exploit chain to gain root privileges.

Persistent Storage

  • Avoid opening the Persistent Storage settings each time after login. (#19410)

  • Solve some cases of failure to activate the Persistent Storage by bumping the unlocking timeout to 120 seconds. (#19432)
