Overview Two new vulnerabilities in the OpenSSH SSH client (CVE-2016-0777 and CVE-2016-0778) allow a malicious or compromised SSH server to induce the client to leak arbitrary memory (including the client’s private keys), and, in some versions of the client, execute arbitrary code on the client system. The client checks the server’s host keys before reaching the point of vulnerability, so a man-in-the-middle attack is not a realistic vector (unless the server’s host keys have already been disclosed).

SmartOS Users New releases of the node.js packages have been added to the 2014Q4 pkgsrc repository. The following latest package releases address the vulnerabilities outlined in this notice: nodejs-0.12.9.tgz nodejs-4.2.3.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: pkg_add http://pkgsrc.joyent.com/packages/SmartOS/2014Q4/x86_64/All/nodejs-0.12.9.tgz pkg_add http://pkgsrc.joyent.com/packages/SmartOS/2014Q4/x86_64/All/nodejs-4.2.3.tgz You can visit the Node.js website for more information about these vulnerabilities, and the specific releases that have been identified as vulnerable.

SmartOS Users As per the table outlined below, users should update to the fixed release of the affected versions. For users running on the older 1.0.0 or 0.9.8 versions of OpenSSL, you are advised to upgrade to later versions of OpenSSL.

Joyent Engineers are aware of the Venom (CVE-2015-3456) security vulnerability in the virtual floppy drive code used by many computer virtualization platforms. This vulnerability may allow an attacker to escape from the confines of an affected virtual machine (VM) guest and potentially obtain code-execution access to the host. Although the flaw exists in our KVM/QEMU in the Joyent software (SmartDataCenter and the Joyent Public Cloud), our architecture runs QEMU inside of an additional secure container with almost no privileges.

The following sections describe the scope of several recently-announced Open SSL Vulnerabilities. We have included actions being taken by Joyent, and actions recommended for customers to take. CVEs specific to OpenSSL version 1.0.2 Joyent has never shipped any versions of OpenSSL version 1.0.2 to customers, either in pkgsrc or as part of SmartDataCenter (SDC). If we do ship 1.0.2 versions in the future, they will be those versions known to contain the recent security fixes.

This notice is to advise Joyent Public Cloud and Smart Data Center customers of the recently identified glibc Linux security issue CVE-2015-0235 (GHOST). This vulnerability can be triggered by the gethostbyname functions, impacting many systems built on Linux. How can you determine whether you are vulnerable? You can scan for this vulnerability using the Qualys Vulnerability Management Cloud Solution as QID 123191. If you think you may be affected, patches are available from all of the Linux vendors starting today.

This notice is to advise Joyent Public Cloud and Smart Data Center customers of the recently identified Kerberos Checksum Vulnerability (CVE-2014-6324) for anyone using Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, and Windows Server 2012 Gold and R2. If you are running a Windows VM, your environment may allow remote authenticated domain users to obtain domain administrator privileges via a forged signature in a ticket.
