(RHSA-2008:0864) Important: tomcat security update

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.
