CVE ID: CVE-2017-5715, CVE-2017-5753, CVE-2017-5754

Dell Technologies is aware of the side-channel analysis vulnerabilities (also known as Meltdown and Spectre) affecting many modern microprocessors that were publicly described by a team of security researchers on January 3, 2018. We encourage customers to review the Security Advisories in the References section for more information.

NOTE: Patch Guidance (update 2018-02-08):

Dell Technologies has received a new microcode from Intel per their advisory that was issued on January 22. Dell Technologies is issuing new BIOS updates for the affected platforms to address Spectre (Variant 2), CVE-2017-5715. The Product Tables have been updated and will be updated as more microcode is released by Intel. If your product has an updated BIOS listed, Dell Technologies recommends you upgrade to that BIOS and apply the appropriate operating system updates to provide mitigation against Meltdown and Spectre.
 
If your product does not have an updated BIOS listed, Dell Technologies still advises that customers should not deploy the previously released BIOS updates and wait for the updated version.

If you have already deployed a BIOS update that could have issues according to Intel's January 22 advisory, in order to avoid unpredictable system behavior, you can revert back to a previous BIOS version. See the tables below.

As a reminder, the Operating System patches are not impacted and still provide mitigation to Spectre (Variant 1) and Meltdown (Variant 3). The microcode update is only required for Spectre (Variant 2), CVE-2017-5715.

  There are two essential components that must be applied to mitigate the above-mentioned vulnerabilities:

  1. System BIOS as per Tables below
  2. Operating System and Hypervisor updates.
We encourage customers to review the appropriate Hypervisor/OS vendor security advisory. The References section below contains links to some of these vendors.

Dell Technologies recommends customers to follow security best practices for malware protection in general to protect against possible exploitation of these analysis methods until any future updates can be applied. These practices include promptly adopting software updates, avoiding unrecognized hyperlinks and websites, protecting access to privileged accounts, and following secure password protocols.

Frequently Asked Questions (FAQ)

Question: How can I protect against these vulnerabilities?
Answer: There are three vulnerabilities associated with Meltdown and Spectre. Customers must deploy an operating system patch from their operating system vendor for all three vulnerabilities. Only Spectre Variant 2 (CVE-2017-5715) requires a BIOS update with the processor vendor-provided microcode. Currently, Intel does not yet have a microcode update available to protect against the Spectre Variant 2 vulnerability.

See table below:

Question: What is Dell Technologies' current recommendation regarding updating the operating system patches?
Answer: See the operating system vendor’s patch guidance links.

Question: Does Dell Technologies have a list of Enterprise products that are not affected?
Answer: Dell Technologies has a list of Enterprise products that are not affected. See the Dell Products requiring no patches or fixes for these three CVE vulnerabilities section.

Question: What do I do if I run a virtual server?
Answer: Both the hypervisor and all guest operating systems must be updated.

Question: Are Internet browsers potentially affected? (JavaScript Variant 2 exploit)?
Answer: Yes Internet browsers can be affected by the Spectre vulnerability and most browsers have provided updated versions or patches to mitigate this potential vulnerability. See links below for Chrome, Internet Explorer, and Mozilla for additional information.

Question: What about iDRAC and PERC?
Answer: Both the PERC and iDRAC are closed systems that do not allow third-party (user) code to run. Spectre and Meltdown both require the ability to run arbitrary code on the processor. Due to this closed code arrangement neither peripheral is at risk of a side-channel analysis microprocessor exploit.

Question: What about appliances? Are there other applications that are not affected?
Answer: Closed systems that do not allow third-party (user) code to run are not vulnerable.

Question: What about the AMD Opteron processors?
Answer: https://www.amd.com/en/corporate/speculative-execution.

Question: When will the BIOS with microcode updates available from Dell Technologies for Intel-based systems?
Answer: Updated BIOSes that contain the Intel microcode security updates are available for PowerEdge 14G, 13G, 12G, and some of the 11G systems.

Question: When will the BIOS be available for converged infrastructure running on PowerEdge technology (VXRail, so forth)
Answer: Dell Technologies is working to validate existing PowerEdge code updates for all converged infrastructure platforms running on PowerEdge technology. Updates are provided as additional information is available.

Question: Will Dell Technologies be factory installing the operating system and hypervisor patches for PowerEdge Servers and converged infrastructure?
Answer: As of March 6, 2018, Dell is factory installing the following versions of operating system updates to help mitigate the Spectre/Meltdown vulnerabilities. These are configured (where possible) for maximum protection (fully enabled). Sometimes, there are newer updates provided by the vendors.  Continue to see the operating system vendor websites for specific configuration guidance and newer updates and configuration options as they become available.

  • VMware ESXi 6.0U3: Rev A08 Build 6921384                (contains VMSA-2018-002 patch)

Question: I have heard that the vulnerability affects microprocessors going back at least 10 years. How far back is Dell offering a BIOS update?
Answer: Dell is working with Intel to provide the required BIOS with microcode patches for PowerEdge systems going back to our 11th generation product line. Any BIOS updates that contain microcode updates for the security fix will be dependent upon the affected processor vendors providing code updates to Dell Technologies.

Question: Will Dell Technologies provides technical support for systems that are out of warranty?
Answer: Dell Technologies does not provide technical support for Dell Technologies PowerEdge servers that do not have a valid support contract. Customers can access publically available support documents on Dell Support regardless of current support contract status.

Question: Will Dell Technologies provides patches for systems that are out of warranty?
Answer: Dell Technologies PowerEdge server products do not require a valid support contract in order to gain access to our support and download pages. PowerEdge server BIOS updates are available on the Dell Technologies support site to all users regardless of current support contract status. See the BIOS section BIOS/Firmware/Driver updates for PowerEdge Server and Networking Products for BIOS availability. Operating system patches should be obtained from your operating system provider see the links in the operating system Patch Guidance section.

Question: What about the new AMD EPYC processors?
Answer: For AMD public statements on Meltdown (CVE-2017-5754) Spectre Variant 1 (CVE-2017-5753) and Spectre Variant 2 (CVE-2017-5715) as they relate to AMD processors, see https://www.amd.com/en/corporate/speculative-execution.
For Spectre Variant 1 (CVE-2017-5753) the applicable operating system patch addresses this issue.

Question: When will BIOS updates be available for AMD EYPC based PowerEdge systems that are affected by Spectre?
Answer: Dell EMC has released BIOS updates for our 14G platforms (R7425, R7415, & R6415) which are available on our product support pages. Factory installs of these BIOS were available on January 17, 2018.

Question: When will the BIOS with Intel microcode updates be factory installed on the Intel based PowerEdge systems?  
Answer: PowerEdge 14G and 13G (except R930) BIOS is targeted to be available by factory install on March 6, 2018.  PowerEdge R930 BIOS is targeted to be available using factory install by March 9, 2018.

Question: Is there a performance impact from these BIOS and operating system updates?
Answer: The key aspect of these attacks relies on speculative execution which is a performance-related feature. Performance impacts vary since they are highly workload-dependent. Dell is working with Intel and other vendors to determine performance impacts as a result of these updates and will address this once available.
