Output spoofing and hangs via Windows device names
Published May 23, 2024 · Updated Aug 2, 2024
Improper Windows device-name handling in GitoxideLabs gitoxide before 0.36.0 allows remote attackers to interrupt or spoof gix output. During clone, gix-ref opens attacker-named refs such as CON as devices, while gix-worktree-state treats matching paths as ordinary files and writes attacker-controlled bytes to them. The flaw is reachable only on Windows when an untrusted repository is cloned or otherwise used; it can block on console input, print deceptive text, or interfere with available devices.
