Overview This notice is to advise Joyent’s Triton Cloud (public cloud) customers, Triton Enterprise software customers and Open Source Triton users of four SmartOS/file system vulnerabilities reported by Cisco Talos.
Description On 13-December-2016, Cisco Talos reported three privilege escalation vulnerabilities that result from exploits on the ioctl() function. Based on our investigation, the exploits are actually not possible as either a regular user or as root from within a zone.
Overview This notice is to advise the user groups identified below of recently-discovered, arbitrary kernel-mode code execution vulnerabilities. These issues were reported directly to Joyent Engineering by an individual user.
Description These high-severity vulnerabilities exist in the core SmartOS platform, and have been present since (at least) OpenSolaris times.
Attackers can potentially exploit certain system calls to obtain root privileges. Input validations for the system calls involved have been hardened to prevent such malicious attempts.
How To Update Your Services SmartOS Users New releases of the Node.js and OpenSSL packages have been added to our pkgsrc repository (see below for specific details). The following latest package releases address the vulnerabilities outlined in this post’s “Original Notice” section:
nodejs-6.7.0.tgz (2016Q3) nodejs-4.6.0.tgz (2014Q4, 2015Q4, 2016Q3) nodejs-0.12.16.tgz (2014Q4, 2015Q4, 2016Q3) nodejs-0.10.47.tgz (2014Q4, 2015Q4, 2016Q3) openssl-1.0.2j.tgz (2015Q4, 2016Q3) openssl-1.0.2i.tgz (2015Q4) openssl-1.0.1u.tgz (2014Q4) If you are running on an older SmartOS image that is using a deprecated pkgsrc repository, you may still try installing the correct fixed package by using the following command (NOTE: please test for any potential incompatibilities on a non-production machine prior to trying this):
How To Update Your Services SmartOS Users New releases of the Node.js packages have been added to the 2016Q1 pkgsrc repository. The following latest package releases address the vulnerabilities outlined in this notice:
nodejs-5.12.0.tgz nodejs-4.4.7.tgz nodejs-0.12.15.tgz nodejs-0.10.46.tgz If you are running on a SmartOS image that is using a different pkgsrc repository, you can still install the above by using the following command (you may want to first test for any potential incompatibilities on a non-production machine):

Overview Introduction This notice is to ensure that all Triton Cloud customers, all on-premises operators of Triton Enterprise (formerly SmartDataCenter or SDC) and all open source Triton users are aware of vulnerabilities reported to us by research contributors at Trend Micro’s Zero Day Initiative, and some discovered by our own Engineering team:
All necessary fixes have been applied to Triton Cloud (formerly Joyent Public Cloud or JPC). No action is required by Triton Cloud customers.
Overview Please read this first
Through HP’s Zero Day Initiative, we have previously been made aware of the three security issues described in this Overview:
These vulnerabilities have already been fixed throughout the Joyent Public Cloud. On-premises Triton (SDC7) software customers can mitigate all of these issues by following the (previously-provided) instructions referenced in the Recommendations/Fixes section below. These three vulnerabilities will be announced on Tuesday, 16-February-2016 at Zero Day’s “Upcoming Advisories”.
