Hi all,  
I run a percona XtraDB cluster the actual version installed percona-xtradb-cluster-server-5.6 5.6.35-26.20-3.  
The mysql version installed is 5.6.35-81.0 and it looks that some security patch are missing [url][Oracle Critical Patch Update Advisory - April 2017](http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618.html#AppendixMSQL%5B/url%5D)  
Is already someone of you guys concerned with this problem?  
Would be appreciated if you can share how are you dealing with this issue.

Many thanks
