RHSA-2007:0876 - Moderate: tomcat security update

Synopsis

Moderate: tomcat security update

Type/Severity

Security Advisory Moderate

Topic

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.

Description

Tomcat is a servlet container for Java Servlet and Java Server Pages technologies.

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 (CVE-2007-2450).

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 (CVE-2007-3385).

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.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
