DescriptionNVD

A race condition in the Nix, Lix, and Guix package managers enables changing the ownership of arbitrary files to the UID and GID of the build user (e.g., nixbld* or guixbuild*). 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.

Analysis

Technical ContextAI

A race condition occurs when the behavior of software depends on the timing of events, such as the order of execution of threads or processes.

RemediationAI

Use proper synchronization mechanisms (locks, mutexes, atomic operations). Implement file locking for filesystem operations. Avoid TOCTOU patterns.
