synopsis: Harden the user sandboxing
significance: significant
issues:
---
The build directory has been hardened against interference with the outside world by nesting it inside another directory owned by (and only readable by) the daemon user.
This is a low severity security fix, [CVE-2024-38531](https://www.cve.org/CVERecord?id=CVE-2024-38531), that was handled through the GitHub Security Advisories interface, and hence was merged directly in commit [2dd7f8f42](https://github.com/NixOS/nix/commit/2dd7f8f42da374d9fee4d424c1c6f82bcb36b393) instead of a PR.
