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
zimbraProxyAllowedDomainsis 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
