GUI manipulation and hang via predictable temporary file
Published Dec 14, 2023 · Updated Aug 2, 2024
Insecure temporary file handling in Budgie Extras before 1.7.1 allows local users to falsify WeatherShow data or hang the panel. WeatherShow.vala deletes and recreates /tmp/_weatherdata while ignoring errors, then reads attacker-controlled contents into the GUI. Another local account can pre-create the path with false data or a FIFO; the latter blocks the applet and can interrupt the same-thread Budgie panel.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=v1.4.0 <v1.7.1
