(RHSA-2013:1134) Moderate: httpd security update

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)

Note: CVE-2013-1862 affects mod_rewrite. In the process of testing this
patch, it was found that enabling mod_rewrite on 64-bit versions of Windows
Server 2008 and Windows Server 2008 R2 running Red Hat JBoss Web Server
2.0.1 could cause an httpd thread to crash, and the httpd process to
restart. This bug is present in the GA release of Red Hat JBoss Web Server
2.0.1, and is not a regression introduced by this patch. This bug may be
resolved in a future update to JBoss Web Server 2.

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 as provided from the Red Hat
Customer Portal are advised to apply this update.
