Vulnerability Description
Scope of this Security Bulletin:

• Any product that McAfee offers that comes bundled with an operating system, either on hardware or as a virtual machine, is covered in this Security Bulletin.  
• Where McAfee software is installed on an operating system provided by the customer, we only list the product here if we are releasing a fix. By default, these products will be protected by the Intel and operating system vendor-provided updates.

McAfee products that ship as appliances or virtual images are vulnerable to these CVEs as they run on affected Linux distributions. These systems are 'closed' as they do not allow multiple users to log on and execute programs of their choice. As such the likelihood of being exploited is considered low.

As with previous related CVEs (Spectre/Meltdown variants), McAfee plans to address these vulnerabilities as part of the regular update cycles for the impacted products. These vulnerabilities have been given the code name "SWAPGS Attack".

For McAfee virtual appliances including instances running in the cloud, make sure that you have applied the vendor fixes to the virtual environment they are running in.

CVE-2019-1125
A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel.

Where can I find a list of all Security Bulletins?
All Security Bulletins are published on our external PSIRT website at http://www.mcafee.com/us/threat-center/product-security-bulletins.aspx > Security Bulletins. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
 
How do I report a product vulnerability to McAfee?
If you have information about a security issue or vulnerability with a McAfee product, visit the McAfee PSIRT website for instructions at http://www.mcafee.com/us/threat-center/product-security-bulletins.aspx > Report a Security Vulnerability.
 
How does McAfee respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any McAfee software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.
 
McAfee only publishes Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.
