CVE-2022-37436: Apache HTTP Server: mod_proxy prior to 2.4.55 allows a backend to trigger HTTP response splitting

[Eric Covener <covener () apache org>]

Severity: moderate

Description:

Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting 
in some headers being incorporated into the response body. If the later headers have any security purpose, they will 
not be interpreted by the client.
