In this blog post, we examine the recent revelations about CPU security vulnerabilities.

The beginning of the new year also brings to light fresh and new CPU security vulnerabilities. Today’s big offenders originate on the hardware side – more specifically, the CPU. The reported hardware kernel bugs allow for direct access to data held in the computer/server’s memory, which in turn might leak sensitive data. Some of the most popular CPUs affected by these bugs are Intel, AMD and ARM.

The most important thing to know is that this vulnerability is not exploitable remotely, and requires that someone execute the malicious code locally. However, take extra precaution when running in virtualized environments (see below for more information).

I think the biggest news from last week was from cPanel – if you haven’t already read the post, please do – on Being a Good Open Source Community Member: Why we hesitated on MySQL 5.7. cPanel anticipated MariaDB being the eventual replacement for MySQL, based on movements from Red Hat, Wikipedia and Google. The advantage focused on transparency around security disclosure, and the added features/improvements. Today though, “MySQL now consistently matches or outpaces MariaDB when it comes to development and releases, which in turn is increasing the demand on us for providing those upgraded versions of MySQL by our users.” And …

As we close out the holiday season, let’s look at some data that tells us how to guarantee a successful Black Friday (from a database perspective).

There are certain peak times of the year where companies worldwide hold their breath in the hope that their databases do not become overloaded or unresponsive. A large percentage of yearly profits are achieved in a matter of hours during peak events. It is critical that the database environment remains online and responsive. According to a recent survey, users will not wait more than 2.5 seconds for a site to load before navigating elsewhere. Percona has partnered with many clients over the years to ensure success during these critical events. Our goal is always to provide our clients with the most responsive, stable open-source database environments in order to meet their business needs.

We’re completing our move of Percona bug tracking into JIRA, and the drop-dead date is December 28, 2017.

For some time now, Percona has maintained both the legacy Launchpad bug tracking system and a JIRA bug tracking system for some of the newer products. The time has come to consolidate everything into the JIRA bug tracking system.

Assuming everything goes according to schedule, on December 28, 2017, we will copy all bug reports in Launchpad into the appropriate JIRA projects (with the appropriate issue state). The new JIRA issue will link to the original Launchpad issue, and the new JIRA issue link is added to the original Launchpad issue. Once this is done, we will then turn off editing on the Launchpad projects.
