RHSA-2008:0648 - Security Advisory

Topic

Updated tomcat packages that fix several security issues are now available
for Red Hat Enterprise Linux 5.

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

Description

Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.

A cross-site scripting vulnerability was discovered in the
HttpServletResponse.sendError() method. A remote attacker could inject
arbitrary web script or HTML via forged HTTP headers. (CVE-2008-1232)

An additional cross-site scripting vulnerability was discovered in the host
manager application. A remote attacker could inject arbitrary web script or
HTML via the hostname parameter. (CVE-2008-1947)

A traversal vulnerability was discovered when using a RequestDispatcher
in combination with a servlet or JSP. A remote attacker could utilize a
specially-crafted request parameter to access protected web resources.
(CVE-2008-2370)

An additional traversal vulnerability was discovered when the
"allowLinking" and "URIencoding" settings were activated. A remote attacker
could use a UTF-8-encoded request to extend their privileges and obtain
local files accessible to the Tomcat process. (CVE-2008-2938)

Users of tomcat should upgrade to these updated packages, which contain
backported patches to resolve these issues.
