Mailman -- cross-site scripting in web interface

Secunia reports:

Two vulnerabilities have been reported in Mailman, which
can be exploited by malicious users to conduct script
insertion attacks.
Certain input passed via the list descriptions is not
properly sanitised before being displayed to the user. This
can be exploited to insert arbitrary HTML and script code,
which will be executed in a user’s browser session in context
of an affected site when the malicious data is being
viewed.
Successful exploitation requires “list owner” permissions.
