Also solves 3 security issues :

  - [ZBX-7703] fixed being able to switch users without
    proper credentials when using HTTP authentication;
    reference CVE-2014-1682

  - [ZBX-6721] fixed LDAP authentication; reference
    CVE-2013-5572

    - [ZBX-7693] fixed admin user being able to update media
      for other users; reference CVE-2014-1685

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
