CVE-2024-35197
MEDIUMCVE-2024-35197 is a medium-severity (CVSS 5.4) CWE-67 vulnerability in gix-worktree-state. O3 Security confirms whether CVE-2024-35197 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
gix refs and paths with reserved Windows device names access the devices
Real-World Exposure
gix-worktree-state🦀gitoxide🦀gix-worktree🦀gitoxide-core🦀gix🦀gix-ref🦀gix-indexReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
gitoxide is a pure Rust implementation of Git. On Windows, fetching refs that clash with legacy device names reads from the devices, and checking out paths that clash with such names writes arbitrary data to the devices. This allows a repository, when cloned, to cause indefinite blocking or the production of arbitrary message that appear to have come from the application, and potentially other harmful effects under limited circumstances. If Windows is not used, or untrusted repositories are not cloned or otherwise used, then there is no impact. A minor degradation in availability may also be possible, such as with a very large file named CON, though the user could interrupt the application.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gix-worktree-state. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update gix-worktree-state to 0.11.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-35197 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-35197 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-35197. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-35197 in your dependencies?
O3 detects CVE-2024-35197 across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
