pyxdg Arbitrary File Overwrite via Race Condition
Race condition in the xdg.BaseDirectory.get_runtime_dir function in pyxdg 0.25 allows local users to overwrite arbitrary files by pre-creating /tmp/pyxdg-runtime-dir-fallback-victim to point to a victim-owned location, then replacing it with a symlink to an attacker-controlled location once the get_runtime_dir function is called.
