<p>
Tomcat is the Apache Jakarta Project's official implementation of Java
Servlets and Java Server Pages.

<description>
<p>
The following vulnerabilities were reported:
</p>
<ul>
<li>Delian Krustev discovered that the JULI logging component does not
properly enforce access restrictions, allowing web application to add
or overwrite files (CVE-2007-5342).</li>
<li>
When the native APR connector is used, Tomcat does not properly handle
an empty request to the SSL port, which allows remote attackers to
trigger handling of a duplicate copy of one of the recent requests
(CVE-2007-6286).</li>
<li>
If the processing or parameters is interrupted, i.e. by an exception,
then it is possible for the parameters to be processed as part of later
request (CVE-2008-0002).</li>
<li>
An absolute path traversal vulnerability exists due to the way that
WebDAV write requests are handled (CVE-2007-5461).</li>
<li>
Tomcat does not properly handle double quote (") characters or %5C
(encoded backslash) sequences in a cookie value, which might cause
sensitive information such as session IDs to be leaked to remote
attackers and enable session hijacking attacks
(CVE-2007-5333).</li>
</ul>
</description>
<impact type="normal">
<p>
These vulnerabilities can be exploited by:
</p>
<ul>
<li>
a malicious web application to add or overwrite files with the
permissions of the user running Tomcat.
</li>
<li>
a remote attacker to conduct session hijacking or disclose sensitive
data.
</li>
</ul>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Tomcat 5.5.x users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/tomcat-5.5.26&quot;</code>
<p>
All Tomcat 6.0.x users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/tomcat-6.0.16&quot;</code>
</resolution>
