Synopsis:          Moderate: httpd security update
Advisory ID:       RHSA-2013:1133-01
Product:           Red Hat JBoss Web Server
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1133.html
Issue date:        2013-08-05
CVE Names:         CVE-2013-1862 CVE-2013-1896 
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat JBoss Web Server 2 for RHEL 5 Server - i386, x86_64
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.

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.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258
