CVE-2023-49344

Local data manipulation via predictable temporary files

Published Dec 14, 2023 · Updated Aug 2, 2024

Insecure temporary file handling in Ubuntu Budgie Budgie Extras 1.4.0 through 1.7.0 allows local users to manipulate Window Shuffler state. Window Shuffler creates and monitors predictable paths under /tmp, trusting attacker-created files or FIFOs as intercomponent state without per-user isolation. Local account access and a concurrently running victim session enable false GUI state, disabled rules, application hangs, or memory exhaustion.
