Description

The Nix, Lix, and Guix package managers fail to properly set permissions when a derivation build fails. This may allow arbitrary processes to modify the content of a store outside of the build sandbox. This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b.
