Multiple vulnerabilities have been found in HAProxy, allowing attackers to execute arbitrary code or cause Denial of Service. HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
I was looking for a solution for graceful reload of haproxy. I have a nginx server running which passes requests to Haproxy and at times I reload the Haproxy configuration. But I am observing that at time of reloading all the existing connections are getting cut off and haproxy backend queue shows 0 requests ( got from socket stats of haproxy ) .
