MySQL Security Webinar: Follow-up Q&A

Thanks to everyone who attended last week’s webinar on MySQL security; hopefully you’ve all gone out and set SELinux to enforcing mode if you weren’t already running that way. If you weren’t able to attend, the recording and slides are available for viewing/download. But now, without further ado, here are the questions which we didn’t […]

MySQL Security: Armoring Your Dolphin

My colleague and teammate Ernie Souhrada will be presenting a webinar on Wednesday, August 21, 2013 at 10 a.m. PDT titled “MySQL Security: Armoring Your Dolphin.” This is a popular topic with news breaking routinely that yet another Internet company has leaked private data of one form or another. Ernie’s webinar will be a great […]

Percona response to recent MySQL security bugs

Recently there have been discussions on several vulnerabilities in MySQL and closely related projects such as MariaDB and Percona Server. Usually we have inherited security fixes from MySQL when we have updated Percona Server to be based off a new Oracle MySQL release. In this case however, Oracle has been incredibly quiet. We’ve been examining […]

Clarification on MySQL security vulnerability

Contrary to initial reports here and here, further investigation has revealed that under some specific and limited circumstances, Percona Server and Percona XtraDB Cluster binaries, similar to other MySQL variants, are susceptible to the security vulnerability in MySQL/MariaDB sql/password.c: 64bit Ubuntu Oneiric (11.10) binaries are vulnerable in Percona Server ONLY on some hardware/virtualization platforms (confirmed […]

MySQL 5.6 security vs ease of use

MySQL 5.6 surely changes the game when it comes to security vs ease of use. Before MySQL 5.6 we would get default MySQL installation being pretty insecure – the user “root” will be created with no password as well as anonymous user with limited access from local host (though still enough to cause DOS attack […]

Security fixes for MySQL 4.0 and 4.1

In Percona Server security fix releases I mentioned patches for MySQL 4.0 and 4.1. I am happy to announce that GoDaddy.com released patches for MySQL 4.0 and MySQL 4.1 under GPL license and you can get them from our Launchpad: for 4.0: lp:~percona-dev/percona-patches/4.0.30 ( or https://launchpad.net/~percona-dev/percona-patches/4.0.30 ) for 4.1: lp:~percona-dev/percona-patches/4.1.24 ( or https://launchpad.net/~percona-dev/percona-patches/4.1.24) Fixed bugs: […]

Using YUM to install specific MySQL/Percona Server versions

Sometimes it is desired to use particular software versions in production, and not necessary the latest ones. There may be several reasons for that, where I think the most common is when a new version should spend some time in testing or a staging environment before getting to production. In theory each new version is […]

File carving methods for the MySQL DBA

This is a long overdue blog post from London’s 44con Cyber Security conference back in September. A lot of old memories were brought to the front as it were; the one I’m going to cover in this blog post is: file carving. So what is file carving? despite the terminology it’s not going to be a […]

(More) Secure local passwords in MySQL 5.6 and up

I log into a lot of different servers running MySQL and one of the first things I do is create a file in my home directory called ‘.my.cnf’ with my credentials to that local mysql instance:

This means I don’t have to type my password in every time, nor am I tempted to include […]
