Package        : mailman
Vulnerability  : cross-site scripting, directory traversal
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-1177 CAN-2005-0202

Two security related problems have been discovered in mailman,
web-based GNU mailing list manager.  The Common Vulnerabilities and
Exposures project identifies the following problems:


    Florian Weimer discovered a cross-site scripting vulnerability in
    mailman's automatically generated error messages.  An attacker
    could craft an URL containing JavaScript (or other content
    embedded into HTML) which triggered a mailman error page that
    would include the malicious code verbatim.


    Several listmasters have noticed unauthorised access to archives
    of private lists and the list configuration itself, including the
    users passwords.  Administrators are advised to check the
    webserver logfiles for requests that contain "/...../" and the
    path to the archives or cofiguration.  This does only seem to
    affect installations running on web servers that do not strip
    slashes, such as Apache 1.3.

For the stable distribution (woody) these problems have been fixed in
version 2.0.11-1woody9.

For the unstable distribution (sid) these problems have been fixed in
version 2.1.5-6.

We recommend that you upgrade your mailman package.

Upgrade Instructions
- - --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
