DESCRIPTION: Apache HTTP Server is vulnerable to HTTP request smuggling,
caused by a chunk header parsing flaw in the apr_brigade_flatten() function.

Apache HTTP server, an attacker could exploit this vulnerability to poison the
web cache, bypass web application firewall protection, and conduct XSS
attacks.
