Zimbra Patch Alert

Hello Zimbra Friends, Customers & Partners,

Zimbra 9.0.0 “Kepler” Patch 18 and 8.8.15 “James Prescott Joule” Patch 25 are here.

Security Recommendation

Zimbra strongly recommends that you review whether the Proxy Servlet is configured to allow a particular host (via zimbraProxyAllowedDomains configuration setting on each class of service). Please make sure:

  • Each entry in zimbraProxyAllowedDomains is a safe and trusted host.
  • There are NO wild card entries like *.webex.com. Instead use specific hosts like example.webex.com.

What’s New:

– Nginx Upgrade from 1.19.0 to 1.20.0
– Openldap Upgrade from 2.4.49 to 2.4.59
– Postfix Upgrade from 3.5.6 to 3.6.1
