Hello All,

A one-click security vulnerability in all versions of Zimbra 
Collaboration Suite has been discovered that could allow an 
unauthenticated attacker to gain access to a Zimbra account.

To fix this vulnerability install the latest Zimbra patch (by using apt 
or yum), the vulnerability is fixed in:

  * Daffodil 10.0.3
  * 9.0.0 Kepler Patch 35
  * 8.8.15 Joule Patch 42

In case you are unable to install the latest patch, you can obtain 
manual mitigation steps via Zimbra Support.

Regards, Barry
