Red Hat Security Advisory

Synopsis: Important: tomcat security update
Advisory ID: RHSA-2007:0326-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0326.html
Issue date: 2007-05-21
Updated on: 2007-05-21
Product: Red Hat Application Server
CVE Names: CVE-2005-2090 CVE-2006-3835 CVE-2006-7195

1. Summary:

Updated tomcat packages that fix multiple security issues are now available
for Red Hat Application Server v2.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Application Server v2 4AS - noarch
Red Hat Application Server v2 4ES - noarch
Red Hat Application Server v2 4WS - 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)

Several applications distributed in the JSP examples displayed unfiltered
values. If the JSP examples are accessible, these flaws could allow a
remote attacker to perform cross-site scripting attacks. (CVE-2006-7195,
CVE-2006-7196)

The default Tomcat configuration permitted the use of insecure
SSL cipher suites including the anonymous cipher suite. (CVE-2007-1858)

Directory listings were enabled by default in Tomcat. Information stored
unprotected under the document root was visible to anyone if the
administrator did not disable directory listings. (CVE-2006-3835)

Users should upgrade to these erratum packages which contain Tomcat version
5.5.23 that resolves these issues. Updated jakarta-commons-modeler
packages are also included which correct a bug when used with Tomcat 5.5.23.

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. Bug IDs fixed (http://bugzilla.redhat.com/):

237086 - CVE-2005-2090 multiple tomcat issues (CVE-2007-0450 CVE-2006-7195 CVE-2006-7196 CVE-2007-1858 CVE-2006-3835)
