cipher block chaining

Hi

A recent Nessus vul scan has highlighted several issues with my customer infrastructure comprising Cisco 3850 IOS-XE switch stacks (WS-C3850-48P  v03.06.00E).

Can anyone please confirm how I can fix the following issue: -

1) 'The SSH server is configured to use Cipher Block Chaining - disable CBC mode & enable CTR or GCM encryption'

Also the scan has highlighted numerous SSL issues which I presume are due to having 'ip http secure-server' configured. Am I correct to assume disabling 'ip http secure-server' will remove these SSL issues?

Many thanks for any help!
