fedora
Calendar Grey February 25, 2023
Dist Fedora Esm H88
Critical security update released for Fedora 37's HAProxy addresses DoS and request smuggling flaws. Please upgrade immediately.
Security fix for CVE-2023-0056, CVE-2023-25725

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
