问题存在于mod_proxy和mod_deflate，没POC，apache发了新版修复了，等达人diff写exp。

Problem Description:

Multiple vulnerabilities has been found and corrected in apache:

The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy
module in the Apache HTTP Server before 2.3.3, when a reverse proxy
is configured, does not properly handle an amount of streamed data
that exceeds the Content-Length value, which allows remote attackers
to cause a denial of service (CPU consumption) via crafted requests
(CVE-2009-1890).

Fix a potential Denial-of-Service attack against mod_deflate or other
modules, by forcing the server to consume CPU time in compressing a
large file after a client disconnects (CVE-2009-1891).

This update provides fixes for these vulnerabilities.
