Updated egroupware packages fix security vulnerabilities:

eGroupware prior to 1.8.006.20140217 is vulnerable to remote file
deletion and possible remote code execution due to user input being
passed to PHP’s unserialize() method (CVE-2014-2027).

eGroupWare before 1.8.007 allows logged in users with administrative
priviledges to remotely execute arbitrary commands on the server.
It is also vulnerable to a cross site request forgery vulnerability
that allows creating new administrative users.
