Splunk and the latest OpenSSL vulnerabilities

Hi Splunk users,

Last Monday, we became aware of a new set of vulnerabilities announced in OpenSSL. We have reviewed the issues, and have determined that we must update the version of OpenSSL we currently ship to address these issues.

Note: Not all the listed issues are of concern for Splunk. For example, we do not use DTLS.  However,  “SSL/TLS MITM vulnerability (CVE-2014-0224)” is relevant to Splunk and should be addressed.

7/1/14: Update

We have now posted the following releases containing the fixed version of OpenSSL:

  • 5.0.9 - This release contains only the OpenSSL update.
  • 6.0.5 - This release contains a number of fixes including the OpenSSL update.
  • 6.1.2 - This release contains one fix in addition to the OpenSSL update.

Fix now available: Splunk and the Heartbleed vulnerability

Dear Splunk users,

This is an update to yesterday’s post on our handling of the OpenSSL Heartbleed vulnerability.  Thank you again for your patience and understanding as we spent the necessary time to prepare and test our fix for this important issue.

Splunk and the Heartbleed SSL vulnerability

(Update: we’ve posted a fix for this issue, see http://blogs.splunk.com/2014/04/10/fix-now-available-splunk-and-the-heartbleed-vulnerability/.)

Dear Splunk users,

As you’re likely aware, a significant vulnerability in OpenSSL, which the security community is calling the “Heartbleed” vulnerability, was discovered and publicized earlier this week. This is not a bug in code that Splunk produced, but rather in a component of a package that is in common use throughout the software industry.

The purpose of this blog post is to inform you about what Splunk is doing to address this issue.   For more detailed information about the vulnerability itself, refer to http://heartbleed.com.

Here’s what you need to know:

What versions of Splunk are affected?

  • Splunk Enterprise versions 6.0, 6.0.1, and 6.0.2 are affected. This includes

Do you use statusboard on your iPad?

Starcher wrote a cool thing!

See this blog post from #splunk denizen starcher explaining how to use Splunk alerting and Dropbox to update a dashboard in statusboard on your iPad: http://www.georgestarcher.com/?p=819.

This makes me think of another “get your Splunk on anywhere your iDevice is” project, the Splunk Everywhere utility written by David Carasso. Check out his blog post about it here: http://blogs.splunk.com/2014/01/29/splunk-alerts-and-charts-on-your-iphone/

Syracuse University’s iSchool IT Girls want to change the world with data

This past Veteran’s Day weekend, I was in Syracuse, NY with fellow Splunker Christy Wilson, attending the 3rd annual IT Girls overnight retreat at Syracuse University’s iSchool. One of the goals of the retreat is to introduce the 100 selected high school girls from around the US to technology concepts, and to inspire them to pursue careers either in, or related to technology–but we were the ones who came away inspired.

The girls travel to the event from all over the country. Most are from neighboring cities including New York, Philadelphia, and the DC area, but the event is expanding its reach–some attendees were from further afield, coming from Texas and Georgia. Some parents also traveled to Syracuse …
