Fedora 31: FEDORA-2020-13fd8b1721 Critical: haproxy Buffer Overflow Exploit

HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high

availability environments. Indeed, it can:

- route HTTP requests depending on statically assigned cookies

- spread load among several servers while assuring server persistence

through the use of HTTP cookies

- switch to backup servers in the event a main one fails

- accept connections to special ports dedicated to service monitoring

- stop accepting connections without breaking existing ones

- add, modify, and delete HTTP headers in both directions

- block requests matching particular patterns

- report detailed status to authenticated users from a URI

intercepted from the application
