CVE-2014-1624: Race Condition
First published: Tue Jan 28 2014(Updated: )
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.
