Updated zarafa packages fix security vulnerabilities:

Robert Scheck reported that Zarafa’s WebAccess stored session
information, including login credentials, on-disk in PHP session
files. This session file would contain a user’s username and password
to the Zarafa IMAP server (CVE-2014-0103).

Robert Scheck discovered that the Zarafa Collaboration Platform has
multiple incorrect default permissions (CVE-2014-5447, CVE-2014-5448,
CVE-2014-5449, CVE-2014-5450).
