RHSA-2007:0328: Important: tomcat security update

First published: Thu May 24 2007(Updated: )

Tomcat is a servlet container for Java Servlet and JavaServer Pages<br>technologies.<br>Tomcat was found to accept multiple content-length headers in a<br>request. This could allow attackers to poison a web-cache, bypass web<br>application firewall protection, or conduct cross-site scripting attacks. <br>(CVE-2005-2090)<br>Tomcat permitted various characters as path delimiters. If Tomcat was used<br>behind certain proxies and configured to only proxy some contexts, an<br>attacker could construct an HTTP request to work around the context<br>restriction and potentially access non-proxied content. (CVE-2007-0450)<br>The implict-objects.jsp file distributed in the examples webapp displayed a<br>number of unfiltered header values. If the JSP examples are accessible,<br>this flaw could allow a remote attacker to perform cross-site scripting<br>attacks. (CVE-2006-7195)<br>Updated jakarta-commons-modeler packages which correct a bug when<br>used with Tomcat 5.5.23 are also included.<br>Users should upgrade to these erratum packages which contain an update to<br>Tomcat that resolves these issues.
