CVSS: 1.0EPSS: 0%CPEs: 7EXPL: 0CVE-2024-51481 – Nix allows macOS sandbox escape via built-in builders
https://notcve.org/view.php?id=CVE-2024-51481
Nix is a package manager for Linux and other Unix systems. On macOS, built-in builders (such as `builtin:fetchurl`, exposed to users with `import <nix/fetchurl.nix>`) were not executed in the macOS sandbox. Thus, these builders (which are running under the `nixbld*` users) had read access to world-readable paths and write access to world-writable paths outside of the sandbox. This issue is fixed in 2.18.9, 2.19.7, 2.20.9, 2.21.5, 2.22.4, 2.23.4, and 2.24.10. Note that sandboxing is not enabled by default on macOS. • https://github.com/NixOS/nix/commit/597fcc98e18e3178734d06a9e7306250e8cb8d74 https://github.com/NixOS/nix/security/advisories/GHSA-wf4c-57rh-9pjg • CWE-693: Protection Mechanism Failure •
CVSS: 5.9EPSS: 0%CPEs: 2EXPL: 0CVE-2024-47174 – Credential leak when credentials are used with `<nix/fetchurl.nix>`
https://notcve.org/view.php?id=CVE-2024-47174
Nix is a package manager for Linux and other Unix systems. Starting in version 1.11 and prior to versions 2.18.8 and 2.24.8, `<nix/fetchurl.nix>` did not verify TLS certificates on HTTPS connections. This could lead to connection details such as full URLs or credentials leaking in case of a man-in-the-middle (MITM) attack. `<nix/fetchurl.nix>` is also known as the builtin derivation builder `builtin:fetchurl`. It's not to be confused with the evaluation-time function `builtins.fetchurl`, which was not affected by this issue. • https://github.com/NixOS/nix/commit/062b4a489e30da9c85fa4ff15cfdd2e51cac7b90 https://github.com/NixOS/nix/commit/5db358d4d78aea7204a8f22c5bf2a309267ee038 https://github.com/NixOS/nix/pull/11585 https://github.com/NixOS/nix/security/advisories/GHSA-6fjr-mq49-mm2c • CWE-287: Improper Authentication •
CVSS: 9.0EPSS: 0%CPEs: 1EXPL: 0CVE-2024-45593 – Nix affected by unsafe NAR unpacking
https://notcve.org/view.php?id=CVE-2024-45593
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. • https://github.com/NixOS/nix/commit/eb11c1499876cd4c9c188cbda5b1003b36ce2e59 https://github.com/NixOS/nix/security/advisories/GHSA-h4vv-h3jq-v493 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2024-38531
Nix is a package manager for Linux and other Unix systems that makes package management reliable and reproducible. A build process has access to and can change the permissions of the build directory. After creating a setuid binary in a globally accessible location, a malicious local user can assume the permissions of a Nix daemon worker and hijack all future builds. This issue was patched in version(s) 2.23.1, 2.22.2, 2.21.3, 2.20.7, 2.19.5 and 2.18.4.

CVSS: 6.3EPSS: 0%CPEs: 4EXPL: 0CVE-2024-27297 – Nix Corruption of fixed-output derivations
https://notcve.org/view.php?id=CVE-2024-27297
Nix is a package manager for Linux and other Unix systems. A fixed-output derivations on Linux can send file descriptors to files in the Nix store to another program running on the host (or another fixed-output derivation) via Unix domain sockets in the abstract namespace. This allows to modify the output of the derivation, after Nix has registered the path as "valid" and immutable in the Nix database. In particular, this allows the output of fixed-output derivations to be modified from their expected content. This issue has been addressed in versions 2.3.18 2.18.2 2.19.4 and 2.20.5. • https://github.com/NixOS/nix/commit/f8170ce9f119e5e6724eb81ff1b5a2d4c0024000 https://github.com/NixOS/nix/security/advisories/GHSA-2ffj-w4mj-pg37 https://hackmd.io/03UGerewRcy3db44JQoWvw • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
