CVE-2013-0253 Apache Maven 3.0.4

Apache Maven 3.0.4 (with Apache Maven Wagon 2.1) has
introduced a non-secure SSL mode by default. This mode
disables all SSL certificate checking, including: host
name verification , date validity, and certificate chain.
Not validating the certificate introduces the possibility
of a man-in-the-middle attack.

All users are recommended to upgrade to Apache Maven 3.0.5
and Apache Maven Wagon 2.4.
