Fedora 29: FEDORA-2018-cb66bc33e6 Critical: HAProxy DoS Fix

fedora
Calendar Grey January 11, 2019
Dist Fedora Esm H88
The upgrade to HAProxy 1.8.15 for Fedora 29 resolves significant security vulnerabilities and improves overall reliability.
Update to 1.8.15

Summary

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
