Mandriva Linux Security Advisory - Scrubber.py in Mailman 2.1.4 through 2.1.6 does not properly handle UTF8 character encodings in filenames of e-mail attachments, which allows remote attackers to cause a denial of service. In addition, these versions of mailman have an issue where the server will fail with an overflow on bad date data in a processed message.
