Updated zabbix packages fix security vulnerabilities:
Zabbix before 2.0.11 allows remote authenticated users to discover the LDAP bind password by leveraging management-console access and reading the ldapbindpassword value in the HTML source code (CVE-2013-5572).
Zabbix before 2.0.11 allows switching users without proper credentials when using HTTP authentication (CVE-2014-1682).
In Zabbix before 2.0.11, the admin user is able to update media for other users (CVE-2014-1685).
