Remediation
Red Hat statement
This issue did not affect the versions of python-django as shipped with Red Hat Update Infrastructure 3 as the vulnerable code is not present. Although Red Hat Satellite 6 uses the vulnerable component python-django, it does not use the module django.utils.numberformat, so it's not possible to trigger this vulnerability. Hence, Red Hat Satellite 6 is not vulnerable to this issue. In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the RHOSP python-django package.
