I had no idea this issue had been identified. While I find this tool very useful, the project is seeming rather questionable to me now.

    I too wish the developer would respond, but I don’t think this is the catastrophe people are making it out to be. One comment seems to explain why these binaries are included:

    Because ventoy supports shim, and by extension secure boot, these files needs to come from a signed Linux distro. In this case they are taken from Fedora releases, and OpenSUSE apparently, as they publish shim binaries and grub binaries signed by their certificate.

        It matters because nobody is going to check the hashes for all of the files match whenever there’s a change so the maintainer can just replace them with whatever he wants.

          that’s what automation is for - nobody is going to manually check them, but anyone is able to automatically set something up to check their hashes in change… the fact that it’s possible that anyone is doing that now that it’s a known issue perhaps makes it less problematic as an attack vector

            That is true, but also nobody is doing it. Just like nobody is verifying Signal’s “reproducible builds”.

              are you sure?

              there could be thousands just waiting for a failure to come out and say “HEY THIS IS DODGY”

                Yea because I tested it myself. Nobody else seems to care, and if they did, I would think there would be a public way to see regular test results regardless.

                I know this exists for some projects, but somehow nothing privacy-sensitive

            The amount of malware you can cram in a source-code patch without drawing attention vs. in a binary is vastly different.

            There’s also the fact that if you want to ship binaries, you can just wget them from source during the build process. Not a perfect solution but much better than what’s ventoy doing. The source code updates works the same in every project because it has to. That’s why this is drawing more attention.

              That’s ok if we are talking about malware publicly shown in the published source code… but there’s also the possibility of a private source-code patch with malware that it’s secretly being applied when building the binaries for distribution. Having clean source code in the repo is not a guarantee that the source code is the same that was used to produce the binaries.

              This is why it’s important for builds to be reproducible, any third party should be able to build their own binary from clean source code and be able to obtain the exact same binary with the same hash. If the hashes match, then you have a proof of the binary being clean. You have this same problem with every single binary distribution, even the ones that don’t include pre-compiled binaries in their repo.

                The problem is not near enough projects support reproducible builds, and many that do aren’t being regularly verified, at least publicly.

      On the contrary: that just goes to show what a fucking catastrophe for software freedom “Secure[sic] Boot” is.

      While this is true, it only requires the shim and grub to be copied for another distro.

      From other comments there are a lot more blobs than just these two.

      It sounds to me as a documentation issue, as the next comment says, simply including a wget script should solve this.
