Package        : mailman
CVE ID         : CVE-2018-0618

Toshitsugu Yoneyama of Mitsui Bussan Secure Directions, Inc. discovered
that mailman, a web-based mailing list manager, 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.

For the stable distribution (stretch), this problem has been fixed in
version 1:2.1.23-1+deb9u3.

We recommend that you upgrade your mailman packages.

For the detailed security status of mailman please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/mailman
