Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the
Apache HTTP Server, the Apache Tomcat Servlet container, Apache
Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster),
Hibernate, and the Tomcat Native library.
It was found that Tomcat would keep connections open after processing
requests with a large enough request body. A remote attacker could
potentially use this flaw to exhaust the pool of available connections
and prevent further, legitimate connections to the Tomcat server.
(CVE-2014-0230)
A flaw was found in the way httpd handled HTTP Trailer headers when
processing requests using chunked encoding. A malicious client could
use Trailer headers to set additional HTTP headers after header
processing was performed by other modules. This could, for example,
lead to a bypass of header restrictions defined with mod_headers.
(CVE-2013-5704)
Multiple flaws were found in the way httpd parsed HTTP requests and
responses using chunked transfer encoding. A remote attacker could
use these flaws to create a specially crafted request, which httpd
would decode differently from an HTTP proxy software in front of it,
possibly leading to HTTP request smuggling attacks. (CVE-2015-3183)
Users of Red Hat JBoss Web Server are advised to upgrade to these
updated packages, which add this enhancement.
