1. Summary:

Updated httpd packages that fix two security issues and one bug are now

2. Relevant releases/architectures:

Red Hat JBoss Web Server 2 for RHEL 6 Server - i386, x86_64

3. Description:

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 the mod_dav module did not correctly strip leading white
space from certain elements in a parsed XML. In certain httpd
configurations that use the mod_dav module (for example when using the
mod_dav_svn module), a remote attacker could send a specially crafted DAV
request that would cause the httpd child process to crash or, possibly,
allow the attacker to execute arbitrary code with the privileges of the
"apache" user. (CVE-2013-6438)

A buffer over-read flaw was found in the httpd mod_log_config module.
In configurations where cookie logging is enabled, a remote attacker could
use this flaw to crash the httpd child process via an HTTP request with a
malformed cookie header. (CVE-2014-0098)

This update also fixes the following bug:

It was discovered that the mod_log_config module, which provides logging of
client requests, truncated cookie values at the first occurrence of an
equal sign ('=') when using the "%{abc}C" syntax in a LogFormat definition.
(ASF Bug 53104)

All users of Red Hat JBoss Web Server 2.0.1 should upgrade to these updated
packages, which contain backported patches to correct these issues.
After installing the updated packages, users must restart the httpd service
for the update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
