A vulnerability exists in the ngx http scgi module and ngx http uwsgi module modules that may result in excessive memory allocation or an over-read of data. When scgi pass or uwsgi pass is configured, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to read the memory of the NGINX worker process or restart it. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
