Two flaws were discovered in mailman, a web-based mailing list manager.
Toshitsugu Yoneyama of Mitsui Bussan Secure Directions, Inc. discovered that mailman is prone to a cross-site scripting flaw allowing a malicious listowner to inject scripts into the listinfo page, due to not validated input in the host_name field.
Hammad Qureshi discovered a content spoofing vulnerability with invalid list name messages in the web UI.
For Debian 8 "Jessie", these problems have been fixed in version 1:2.1.18-2+deb8u3.
