Updated smack packages fix security vulnerabilities:
The ServerTrustManager component in the Ignite Realtime Smack XMPP API before 4.0.0-rc1 does not verify basicConstraints and nameConstraints in X.509 certificate chains from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate chain (CVE-2014-0363).
The Ignite Realtime Smack XMPP API 4.x before 4.0.2, and 3.x and 2.x when a custom SSLContext is used, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate (CVE-2014-5075).
