*** This bug is a security vulnerability *** You have been subscribed to a public security bug by Mike Salvatore (mikesalvatore):
I've come across a problem where I am able to perform several tasks from the lock screen which should not be possible. This includes: - Viewing desktop windows currently running as the logged-in user - Launching programs as the logged-in user - Closing windows of running programs - Enabling/disabling network interfaces and joining networks I don't believe there's a way to interact with the running programs - it's only possible to start a program and view its preview thumbnail. Another note is that I had to press Super+L twice to lock the screen, which has been mentioned in other recent bugs. The unfortunate part is that my PC has been running for days and I have absolutely no idea how I got it into this state. I upgraded it from 18.04 to 18.10 earlier this week. It was a clean 18.04 install from a few months back. I haven't done anything that I would consider a desktop customisation. I've taken some crude hand-held video of the issue. https://youtu.be/TjH9KUjA6pY I could not show the entire Thunderbird window as it displayed my email address. However it's there. ** Affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- Ability to launch/view apps from lock screen https://bugs.launchpad.net/bugs/1805134 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
