Description
Updated tomcat5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.
A flaw was found in the way Tomcat handled the Transfer-Encoding header in HTTP requests. A specially crafted HTTP request could prevent Tomcat from sending replies, or cause Tomcat to return truncated replies, or replies containing data related to the requests of other users, for all subsequent HTTP requests. (CVE-2010-2227)
The Tomcat security update RHSA-2009:1164 did not, unlike the erratum text stated, provide a fix for CVE-2009-0781, a cross-site scripting (XSS) flaw in the examples calendar application. With some web browsers, remote attackers could use this flaw to inject arbitrary web script or HTML via the 'time' parameter. (CVE-2009-2696)
Two directory traversal flaws were found in the Tomcat deployment process. A specially crafted WAR file could, when deployed, cause a file to be created outside of the web root into any directory writable by the Tomcat user, or could lead to the deletion of files in the Tomcat host's work directory. (CVE-2009-2693, CVE-2009-2902)
Users of Tomcat should upgrade to these updated packages, which contain backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.
Solution
Update the affected packages.
