RHEL 4 : tomcat in Satellite Server (RHSA-2009:1616)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated tomcat packages that fix several security issues are now
available for Red Hat Network Satellite Server 5.2 and 5.3.

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

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

This update corrects several security vulnerabilities in the Tomcat
component shipped as part of Red Hat Network Satellite Server. In a
typical operating environment, Tomcat is not exposed to users of
Satellite Server in a vulnerable manner: By default, only Satellite
Server applications are running on Tomcat. This update will reduce
risk in unique Satellite Server environments.

It was discovered that the Red Hat Security Advisory RHSA-2007:1069
did not address all possible flaws in the way Tomcat handles certain
characters and character sequences in cookie values. A remote attacker
could use this flaw to obtain sensitive information, such as session
IDs, and then use this information for session hijacking attacks.
(CVE-2007-5333)

Note: The fix for the CVE-2007-5333 flaw changes the default cookie
processing behavior: With this update, version 0 cookies that contain
values that must be quoted to be valid are automatically changed to
version 1 cookies. To reactivate the previous, but insecure behavior,
add the following entry to the '/etc/tomcat5/catalina.properties'
file :

org.apache.tomcat.util.http.ServerCookie.VERSION_SWITCH=false

It was discovered that request dispatchers did not properly normalize
user requests that have trailing query strings, allowing remote
attackers to send specially-crafted requests that would cause an
information leak. (CVE-2008-5515)

A flaw was found in the way the Tomcat AJP (Apache JServ Protocol)
connector processes AJP connections. An attacker could use this flaw
to send specially-crafted requests that would cause a temporary denial
of service. (CVE-2009-0033)

It was discovered that the error checking methods of certain
authentication classes did not have sufficient error checking,
allowing remote attackers to enumerate (via brute-force methods)
usernames registered with applications running on Tomcat when
FORM-based authentication was used. (CVE-2009-0580)

It was discovered that web applications containing their own XML
parsers could replace the XML parser Tomcat uses to parse
configuration files. A malicious web application running on a Tomcat
instance could read or, potentially, modify the configuration and
XML-based data of other web applications deployed on the same Tomcat
instance. (CVE-2009-0783)

Users of Red Hat Network Satellite Server 5.2 and 5.3 are advised to
upgrade to these updated tomcat packages, which contain backported
patches to resolve these issues. Tomcat must be restarted for this
update to take effect.
