The “Ghost” vulnerability (CVE-2015-0235) in the gethostbyname functions of the GNU C Library (glib), which is commonly found in Linux based operating systems, affects applications calling this function. In some special instances, the successful exploitation of this vulnerability could allow an attacker to perform remote code execution on a targeted system.
Following the release of this vulnerability, we immediately initiated a review of EMC Information Infrastructure and RSA products to assess any potential impact. We have published knowledgebase articles on our customer accessible support websites that reflect the most up to date information from our review along with remediation plans, where needed.
For information on EMC products, including Isilon OneFS, please visit and bookmark KB article 197461 (log in to the EMC Online Support site is required).
We will continue to update the information as our review and remediation continues using our standard customer communication channels, such as the KB article above, and at the EMC Product Security Blog.
If customers have trouble accessing the articles, they can reach out to EMC support at firstname.lastname@example.org.
When we launched the EMC® Isilon® Uptime Bulletin in 2013, each issue was published in a PDF format that could be downloaded from the EMC Online Support site. Because the Uptime Bulletin contains timely information, such as OneFS target code, tips, and the latest firmware releases, we wanted to deliver this information to our customers in a more direct way.
Beginning this year, new Uptime Bulletin content is published to the Uptime Information Hub on the Isilon online community. You can now locate useful information about best practices, OneFS patches, and the latest OneFS and firmware releases, at a glance. The Uptime Information Hub is continuously updated with new information. So be sure to bookmark this page and check it regularly.
New uptime OneFS topic articles
Every quarter, we develop Uptime Bulletin articles that offer tips and best practice information about using OneFS. Here is a summary of new articles that you can now read on the Uptime Information Hub.
Todd Dillon, Senior Director of Software Engineering, explains how Isilon Storage Division uses the EMC Total Customer Experience process to triage every customer-impacting event in OneFS that happens worldwide. Learn how this three-phase process helps to drive continuous improvements with quality assurance (QA) and how maintenance releases (MRs) are determined.
Planning OneFS Upgrades with Global Namespace Acceleration (GNA) Nodes GNA is a OneFS feature that helps you increase performance by using solid state drives (SSDs) to store metadata for read-only purposes. If you use the GNA feature and are planning to upgrade to OneFS 7.0 and later, there are important considerations you need to make. Learn how to verify that your cluster meets minimum requirements for GNA before you upgrade.
Performance Monitoring and Planning Basic performance measurement knowledge of your current Isilon cluster can help you in understanding how adding new volumes or workloads will impact performance. This article walks you through how to perform a workload analysis, and provides best practice information about when to perform this type of analysis.
If you have article feedback or comments, please leave a comment on the Isilon community. You can also review the PDF versions of past issues of the Uptime Bulletin by visiting the EMC Online Support site.
In March, the next Hacker How-To series will focus on cluster capacity and performance.
Over the course of four-weeks, there will be tweets on @EMCIsilon and new blog articles that point you to resources about cluster capacity. Our goal is to link you to currently available videos and white papers, and new content, to help you understand and manage cluster capacity for optimal performance.
We really appreciate your feedback about topics of interest. We’ll continue to work on creating content for our Isilon Community and ISI Knowledge blog that addresses the following popular topics:
Security (permissions, authentication, and role-based access control)
Administrative tasks (upgrades, monitoring, maintenance, and cluster health)
Multiprotocol support (shares, exports, home directories, and permissions)
Compliance (the most specified topic from our “other” responses)
Social media channels
We were also curious to see if there was a preference for social media channels. The results were as expected among our audience, and we’ll continue to use this blog, the Isilon Community, and our Twitter handle as our main social media channels for providing Isilon support content.
We appreciate your time and participation in our survey. If you have questions or feedback about this blog, contact us at email@example.com.
Here are new customer support documents that were published in December, which include several KB articles about EMC® Isilon® SyncIQ policies and new Isilon Community blog posts published that were written by Isilon experts. You can also review the most viewed KB articles on the EMC Online Support site.
Happy New Year! I hope you had a wonderful holiday season!
December was a busy month. I recently shared a survey about which EMC® Isilon® OneFS® topics you would like to learn more about. I’ll announce the survey results and the new Hacker How-To series topic next week.
We also published two videos in December that you can view now.
