please take a look at the following patch by Andreas Jaggi: https://lists.quagga.net/pipermail/quagga-dev/2017-September/033284.html Since applying it, our routers have not been hit with this problem again. If you must rely on distro packages, you may want to draw the distro package maintainer's attention to this patch. The workaround with as-path access-list restricting the number of as path components as noted in https://lists.quagga.net/pipermail/quagga-users/2017-September/014839.html will only help the routers _behind_ the one applying this access-list. A router receiving such a malformed AS path from outside will still show this problem.
