According to LP#1100282¹, Keystone and Neutron are supposed to not be vulnerable with different fixes than Nova. Since all the solutions are different, I'm not sure it covers the problem in its entirety in all cases. I see 2 options: 1. Put effort to move all projects to defusedxml 2. Since XML API are going to be deprecated (at least in Nova), move xmlutils to Nova and be done with it. Solution 1 requires a lot more effort, and I wonder if it's worth it. ¹ https://bugs.launchpad.net/bugs/1100282 -- Julien Danjou // Free Software hacker // http://julien.danjou.info
