(RHSA-2008:0862) Important: tomcat security update

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

The default security policy in the JULI logging component did not restrict
access permissions to files. This could be misused by untrusted web
applications to access and write arbitrary files in the context of the
Tomcat process. (CVE-2007-5342)

A directory traversal vulnerability was discovered in the Apache Tomcat
webdav servlet. Under certain configurations, this allowed remote,
authenticated users to read files accessible to the local Tomcat process.
(CVE-2007-5461)

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.
