Red Hat Security Advisory
Synopsis: Moderate: tomcat security update
Advisory ID: RHSA-2008:0195-01
Product: Red Hat Developer Suite v.3
Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0195.html
Issue date: 2008-04-28
CVE Names: CVE-2007-3382 CVE-2007-3385
Updated tomcat packages that fix multiple security issues are now available
for Red Hat Developer Suite 3.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Developer Suite v.3 (AS v.4) - noarch
Tomcat is a servlet container for Java Servlet and Java Server Pages
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 directory traversal vulnerability existed in the Apache Tomcat webdav
servlet. This allowed remote attackers to remote authenticated users to
read accessible to the local user running the tomcat process (CVE-2007-5461).
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).
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.
This update is available via Red Hat Network. Details on how to use
