** Description changed: # lsb_release -rd Description: Ubuntu 22.04 LTS Release: 22.04 # apt-cache policy gnome-shell gnome-shell: Installed: 42.0-2ubuntu1 Candidate: 42.0-2ubuntu1 Version table: *** 42.0-2ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 100 /var/lib/dpkg/status Ubuntu is installed on a laptop. Within five minutes of inactivity, the screen lock activates and locks the system. Computer is secured. 10 minutes later, my cat (her name is Loaf) comes up to the laptop and sits down on the keyboard. This activates a screen reader. (Shortcut is Alt + Super + S) What I've expected: Screen reader would start reading the contents of a lock screen What happened: Screen reader app started reading contents of a Brave Browser window that was opened on my desktop. It read all tabs and proceeded reading the opened web page. I've reported this bug at secur...@ubuntu.org and got the following answer: > Nice find - I am able to reproduce this locally in Ubuntu 22.04 LTS too > - I suspect this is a vulnerability in gnome-shell as it is > responsible for handling the lock screen in standard Ubuntu. As per further directions, I'm posting this bug here and in gnome repo. P.S. I expect Loaf being credited for this find. She really likes treats. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu82 + Architecture: amd64 + CasperMD5CheckResult: pass + CurrentDesktop: ubuntu:GNOME + DisplayManager: gdm3 + DistroRelease: Ubuntu 22.04 + InstallationDate: Installed on 2021-10-24 (201 days ago) + InstallationMedia: Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012) + Package: gnome-shell 42.0-2ubuntu1 + PackageArchitecture: amd64 + ProcEnviron: + TERM=xterm-256color + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/usr/bin/zsh + ProcVersionSignature: Ubuntu 5.15.0-27.28-generic 5.15.30 + RelatedPackageVersions: mutter-common 42.0-3ubuntu2 + Tags: wayland-session jammy + Uname: Linux 5.15.0-27-generic x86_64 + UpgradeStatus: Upgraded to jammy on 2022-04-28 (15 days ago) + UserGroups: adm cdrom dip docker libvirt lpadmin lxd plugdev sambashare sudo + _MarkForUpload: True ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1972889/+attachment/5589685/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1972889 Title: Screen reader reads the data while computer is locked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1972889/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
