GNU Mailman 1.1

The password generation in mailman before 2.1.5 generates only 5 million unique passwords, which makes it easier for remote attackers to guess passwords via a brute force attack.

Mailman 1.1 allows list administrators to execute arbitrary commands via shell metacharacters in the %(listname) macro expansion.

The attachment scrubber (Scrubber.py) in Mailman 2.1.5 and earlier, when using Python's library email module 2.5, allows remote attackers to cause a denial of service (mailing list delivery failure) via a multipart MIME message with a single part that has two blank lines between the first boundary and the end boundary.

Unknown vulnerability in the mail command handler in Mailman before 2.0.14 allows remote attackers to cause a denial of service (crash) via malformed e-mail commands.

Multiple cross-site scripting (XSS) vulnerabilities in Cgi/confirm.py in GNU Mailman 2.1.14 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) full name or (2) username field in a confirmation message.

Cross-site scripting (XSS) vulnerability in the driver script in mailman before 2.1.5 allows remote attackers to inject arbitrary web script or HTML via a URL, which is not properly escaped in the resulting error page.
