## Description

Nix is a package manager for Linux and other Unix systems. A bug in Nix
2.24 prior to 2.24.6 allows a substituter or malicious user to craft a NAR
that, when unpacked by Nix, causes Nix to write to arbitrary file system
locations to which the Nix process has access. This will be with root
permissions when using the Nix daemon. This issue is fixed in Nix 2.24.6.
