RabbitMQ downloads binary over http without verification

Bug #1791674 reported by Joshua Padman
This bug affects 1 person
Affects Status Importance Assigned to Milestone
Fix Released

Bug Description


Recently it was seen that Kolla was including a RabbitMQ plugin which is downloaded from the RabbitMQ website using HTTP. This file is then included without validation.

This could allow for the injection of code during the build. The website and download is also served on HTTPS with a valid certificate, which should be sufficient mitigation in many cases. However, verification of the binary via checksum would be even better.

Code affected:

There is a current git that may mitigate this for debian installs:

Downstream at Red Hat we will most likely be removing the download and not using the plugin moving forward.

The following CVE was assigned CVE-2018-14620. We are working to ship fixes soon.

Spoke with Martin André about this bug and the potential for others like it. The bug is not particular serious and it would be good to open discussion about this and other potential bugs. Therefore I have set it to a "public security" bug.

I was unable to link the CVE as it was listed as invalid. Will try again soon.

    Download binaries more securely

    Obtain binaries from encrypted source when we're unable to check for
    their signatures. This should provide better security than downloading
    the files over HTTP but does not replace signature verification or file
    integrity check.
