Updated httpd packages that fix two security issues 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. A flaw was found in the way the mod_dav module of the Apache HTTP Server handled merge requests. An attacker could use this flaw to send a crafted merge request that contains URIs that are not configured for DAV, causing the httpd child process to crash. (CVE-2013-1896) It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user. (CVE-2013-1862) Warning: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). 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.
