http://secunia.com/advisories/21732/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Spoofing, DoS

WHERE:

SOFTWARE:
Mailman 2.x

DESCRIPTION:
Some vulnerabilities have been reported in Mailman, which can be
exploited by malicious people to conduct cross-site scripting and
phishing attacks, and cause a DoS (Denial of Service).

1) An error in the logging functionality can be exploited to inject a
spoofed log message into the error log via a specially crafted URL.

Successful exploitation may trick an administrator into visiting a
malicious web site.

2) An error in the processing of malformed headers which does not
follow the RFC 2231 standard can be exploited to cause a DoS (Denial
of Service).

3) Some unspecified input isn't properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

SOLUTION:
The vulnerabilities have been fixed in version 2.1.9rc1 and will also
be fixed in the upcoming 2.1.9 version soon.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Moritz Naumann.
