Updated httpd packages that fix two security issues and one bug are now available for Red Hat JBoss Web Server 2.0.1 for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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 β€˜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 (β€˜=’) when using the β€˜%{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.
