Hello Violeta,
Thanks for the update. We just picked 7.0.76.
Wanted to know if there is an important fix in 7.0.77 version and can users
face issue if they chose to be on 7.0.76.
Just wanted to know if any particular reason because release time between
76 and 77 is short?

Hi All
This vulnerability (CVE-2016-6816) is said to be "Affects: 9.0.0.M1 to

Hi All,
My project is using tomcat 7.0.70, JDK 1.7.0_101 and is based on linux OS
We have been using BIO connectors.
1. I need help to find out how to provide user specified DH parameter to

Thanks Mark.
It appears it is client (3rd party which requests to tomcta) to choose the
cipher while negotiating. We can use SSLHonorCipherOrder
to enforce the server's cipher order.
I guess i got my answer.

Hi Users and Tomcat team,
Port 8443 on my product is configured for Tomcat and accepts inbound
traffic from 3rd parties.
In the TLS handshake, Tomcat chooses TLS_RSA_WITH_AES_256_CBC_SHA over some
of the more secure cipher options offered by the 3rd party. The
3rd party offers a list of 66 cipher
