RHSA-2007:0327: Important: tomcat security update
Tomcat is a servlet container for Java Servlet and JavaServer Pagestechnologies.Tomcat was found to accept multiple content-length headers in arequest. This could allow attackers to poison a web-cache, bypass webapplication firewall protection, or conduct cross-site scripting attacks. (CVE-2005-2090)Tomcat permitted various characters as path delimiters. If Tomcat was usedbehind certain proxies and configured to only proxy some contexts, anattacker could construct an HTTP request to work around the contextrestriction and potentially access non-proxied content. (CVE-2007-0450)The implict-objects.jsp file distributed in the examples webapp displayed anumber of unfiltered header values. If the JSP examples were accessible,this flaw could allow a remote attacker to perform cross-site scriptingattacks. (CVE-2006-7195)Users should upgrade to these erratum packages which contain an update toTomcat that resolves these issues. Updated jakarta-commons-modelerpackages are also included which correct a bug when used with Tomcat 5.5.23.
