CVE-2023-49345

Desktop spoofing and panel denial via predictable file

Published Dec 14, 2023 · Updated May 21, 2025

Improper temporary-file handling in Ubuntu Budgie Budgie Extras 1.4.0 through 1.7.0 allows local users to alter displayed break data. The Takeabreak applet reads /tmp/nextbreak_, splits its attacker-controlled contents on a period, and displays the first element as the next break time. Any local account can pre-create the world-editable path to spoof the desktop display or substitute a FIFO that blocks the applet and can interrupt the Budgie panel.
