RHSA-2007:0876 - Security Advisory
Moderate: tomcat security update
Security Advisory: Moderate
Updated tomcat packages that fix multiple security issues are now available
for Red Hat Application Server v2.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Tomcat is a servlet container for Java Servlet and Java Server Pages
Tomcat incorrectly handled "Accept-Language" headers that do not conform to
RFC 2616. An attacker was able to perform cross-site scripting (XSS)
attacks in certain applications (CVE-2007-1358).
Some JSPs within the 'examples' web application did not escape user
provided data. If the JSP examples were accessible, this flaw could allow a
remote attacker to perform cross-site scripting attacks (CVE-2007-2449).
Note: it is recommended the 'examples' web application not be installed on
a production system.
The Manager and Host Manager web applications did not escape user provided
data. If a user is logged in to the Manager or Host Manager web
application, an attacker could perform a cross-site scripting attack
Tomcat was found treating single quote characters -- ' -- as delimiters in
cookies. This could allow remote attackers to obtain sensitive information,
such as session IDs, for session hijacking attacks (CVE-2007-3382).
It was reported Tomcat did not properly handle the following character
sequence in a cookie: \" (a backslash followed by a double-quote). It was
possible remote attackers could use this failure to obtain sensitive
information, such as session IDs, for session hijacking attacks
A cross-site scripting (XSS) vulnerability existed in the Host Manager
Servlet. This allowed remote attackers to inject arbitrary HTML and web
script via crafted requests (CVE-2007-3386).
Users of Tomcat should update to these erratum packages, which contain
backported patches and are not vulnerable to these issues.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
