Updated tomcat packages that fix multiple security issues and a bug are now
available for Red Hat Developer Suite 3.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Tomcat is a servlet container for Java Servlet and JavaServer Pages
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.
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)
The implict-objects.jsp file distributed in the examples webapp displayed a
number of unfiltered header values. If the JSP examples are accessible,
this flaw could allow a remote attacker to perform cross-site scripting
Updated jakarta-commons-modeler packages which correct a bug when
used with Tomcat 5.5.23 are also included.
Users should upgrade to these erratum packages which contain an update to
Tomcat that resolves these issues.
