CVE-2024-47174 Open this link in a new tabHow to fix?
Upgrade nixos/nix to version 2.24.8 or higher.
Overview
Affected versions of this package are vulnerable to Improper Authentication due to the improper verification of TLS certificates in the builtin:fetchurl derivation builder. An attacker can intercept HTTPS connections and potentially access sensitive information by exploiting this vulnerability in a man-in-the-middle attack.
Note:
This is only exploitable if the user has a netrc file for authentication or relies on derivations with impureEnvVars set to use credentials from the environment.
Workaround
This vulnerability can be mitigated by using pkgs.fetchurl from Nixpkgs with impureEnvVars and curlOpts as needed.
