## 🧠 About the Vulnerability

**CVE-2025-32463** is a local privilege escalation vulnerability affecting `sudo` versions **1.9.14 to 1.9.17**.

The flaw resides in the way `sudo` handles the `--chroot` (`-R`) option introduced in 1.9.14. It allows an unprivileged user to craft a fake `nsswitch.conf` inside a controlled chroot path, forcing `sudo` (running as root) to load an arbitrary **NSS library** and execute code as root.

---

## ✅ Affected Versions

- `sudo` **≥ 1.9.14** and **< 1.9.17p1**
- Unaffected:  
  - Versions **< 1.9.14** (feature not present)  
  - Versions **≥ 1.9.17p1** (vulnerability patched)

---

## 🚩 Requirements

- A vulnerable version of `sudo` (see above)
- `gcc` installed
- The user can run `sudo -R` with an arbitrary directory *(some setups restrict this)*
