Red Hat Security Advisory 2016-1425-01 - Nginx is a web and proxy server with a focus on high concurrency, performance, and low memory usage. The following packages have been upgraded to a newer upstream version: rh-nginx18-nginx. Security Fix: A NULL pointer dereference flaw was found in the nginx code responsible for saving client request body to a temporary file. A remote attacker could send a specially crafted request that would cause nginx worker process to crash.
