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: 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 •
