Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the mailman packages.

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