Severity:	normal
Title:	Tomcat: Multiple vulnerabilities
Date:	04/10/2008
Bugs:	#196066, #203169
ID:	200804-10

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	Architecture(s)
www-servers/tomcat	< 6.0.16	>= 5.5.26	All supported architectures

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"
