RHSA-2007:0328 - Security Advisory
Important: tomcat security update
Security Advisory: Important
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.
Tomcat is a servlet container for Java Servlet and JavaServer Pages
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.
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 JSP examples are accessible,
this flaw could allow a remote attacker to perform cross-site scripting
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.
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
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:
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
