"The remote Debian 11 / 12 host has a package installed that is affected by a vulnerability as referenced in the dsa-5669
advisory.

  - 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. Users are advised to upgrade. There are no
    known workarounds for this vulnerability. (CVE-2024-27297)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
