Synopsis
=======
Multiple vulnerabilities in Tomcat may lead to local file overwriting,
session hijacking or information disclosure.
Background
=========
Tomcat is the Apache Jakarta Project's official implementation of Java
Servlets and Java Server Pages.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-servers/tomcat < 6.0.16 *>= 5.5.26
>= 6.0.16
Description
==========
The following vulnerabilities were reported:
* 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).
* 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).
* 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).
* An absolute path traversal vulnerability exists due to the way that
WebDAV write requests are handled (CVE-2007-5461).
* 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).
Impact
=====
These vulnerabilities can be exploited by:
* a malicious web application to add or overwrite files with the
permissions of the user running Tomcat.
* a remote attacker to conduct session hijacking or disclose
sensitive data.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Tomcat 5.5.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-5.5.26"
All Tomcat 6.0.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.16"
