Red Hat Developer Suite 3 RHSA-2007:0328-01 Critical: Tomcat Update

Updated tomcat packages that fix multiple security issues and a bug are now available for Red Hat Developer Suite 3. 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. . - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Important: tomcat security update Advisory ID: RHSA-2007:0328-01 Advisory URL: https://access.redhat.com/errata/RHSA-2007:0328.html Issue date: 2007-05-24 Updated on: 2007-05-24 Product: Red Hat Developer Suite v.3 CVE Names: CVE-2005-2090 CVE-2006-7195 CVE-2007-0450 - ---------------------------------------------------------------------1. Summary: 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. 2. Relevant releases/architectures: Red Hat Developer Suite v.3 (AS v.4) - noarch Red Hat Developer Suite v.3 (ES v.4) - noarch Red Hat Developer Suite v.3 (WS v.4) - noarch 3. Problem description: Tomcat is a servlet container for Java Servlet and JavaServer Pages technologies. 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) The implict-objects.jsp file distributed in the examples webapp displayed a number of unfiltered header values. If the JSPexamples are accessible, this flaw could allow a remote attacker to perform cross-site scripting attacks. (CVE-2006-7195) 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. 4. Solution: Note: /etc/tomcat5/web.xml has been updated to disable directory listing by default. If you have previously modified /etc/tomcat5/web.xml, this change will not be made automatically and you should manually update the value for the "listings" parameter to "false". Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
