A few days ago Nginx announced there is a security bug therefore they have been released two new versions. Further information about this security bug is here. I pushed new Nginx rpms for Fedora and EPEL after I had noticed about this security issue. They are in testing repository now, I hope it will be pushed to stable soon.
Drupal security team also announced there are new versions. I updated Drupal as well, you can get them from testing repositories.
