    Hello,

    will be this update also available for Percona XtraDB Cluster? We are currently using latest version available 5.5.41. Is there a plan to implenet security fixes and new features also in MySQL product line 5.5?

    Thanks in advance

    Pavel

    the email you received likely states on Percona Server and not XtraDB Cluster. It will come out after they give it a good testing.

    Hi Pavel and Rob,

    shockwavecs is correct.

    Here is a blog post concerning the CVE-2016-6662 vulnerability: https://www.percona.com/blog/2016/09/12/database-affected-cve-2016-6662/

    The update for Percona XtraDB Cluster is planned, but not yet released.

    Hi everyone,

    Excuse me if this is the wrong place to ask this but following the blog post regarding the CVE-2016-6662 vulnerability, we are currently using Percona-XtraDB-Cluster-server-56-5.6.26. After checking for an update i get this output

    Transaction Summary

    Is there a guide for a safe upgrade from 5.6.26 to 5.6.30 or do i even need one? Can you provide advice on how to proceed on updating a production cluster, should i do a rolling upgrade or bring down the whole cluster before doing the update

    Thanks for the time

    Regards

    This package is still affected by the CVE bug. So you'll have to upgrade twice. We are waiting for the fixed one (could be 5.6.30 or higher).

    For the upgrade, it's pretty strait forward, but you can check if there is specific changes by looking at the MySQL changelog between 5.6.26 and 5.6.30. Then you just upgrade one node at a time, and do wait for the node to be in sync again. The best way to check this is to
    tail -f /var/log/mysql/mysql.log
    
    and wait for the line
    WSREP: Shifting JOINED -> SYNCED
    
    . You also have some tutorials on this very website.

    It seems that 5.6.30-25.16-2.jessie has just been set to Debian's repository. Thanks!
