Ubuntu 4.10 : mailman vulnerabilities (USN-59-1)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Florian Weimer discovered a cross-site scripting vulnerability in
mailman's automatically generated error messages. An attacker could
craft an URL containing JavaScript (or other content embedded into
HTML) which triggered a mailman error page. When an unsuspecting user
followed this URL, the malicious content was copied unmodified to the
error page and executed in the context of this page.

Juha-Matti Tapio discovered an information disclosure in the private
rosters management. Everybody could check whether a specified email
address was subscribed to a private mailing list by looking at the
error message. This bug was Ubuntu/Debian specific.

Important note :

There is currently another known vulnerability: when an user
subscribes to a mailing list without choosing a password, mailman
automatically generates one. However, there are only about 5 million
different possible passwords which allows brute-force attacks.

A different password generation algorithm already exists, but is
currently too immature to be put into a stable release security
update. Therefore it is advisable to always explicitly choose a
password for subscriptions, at least until this gets fixed in Warty
Warthog.

See https://bugzilla.ubuntu.com/4892 for details.

Solution :

Update the affected mailman package.

Risk factor :

Medium / CVSS Base Score : 4.3
