(RHSA-2007:0360) Important: jbossas security update

Tomcat is a servlet container for Java Servlet and JavaServer Pages
technologies.

This update addresses the following issues:

Tomcat was found to accept multiple content-length headers in a
request. This could allow attackers to poison a web-cache, bypass web
application firewall protection, or conduct cross-site scripting attacks.
(CVE-2005-2090)

Tomcat permitted various characters as path delimiters. If Tomcat was used
behind certain proxies and configured to only proxy some contexts, an
attacker could construct an HTTP request to work around the context
restriction and potentially access non-proxied content. (CVE-2007-0450)

Users should upgrade to these erratum packages, which contain an update to
jbossas to include a version of Tomcat that resolves these issues. Updated
jakarta-commons-modeler packages are also included which correct a bug when
used with Tomcat 5.5.23.
