Scope of this Security Bulletin:
As with previous related CVEs (Spectre/Meltdown variants), we plan to address these vulnerabilities as part of the regular update cycles for the impacted products. These vulnerabilities have been given the code name "ZombieLoad."
For our virtual appliances, including instances running in the cloud, ensure that you have applied the vendor fixes to the virtual environment they are running in.
The table below shows the status of all currently supported products where we provide the operating system. The table will be populated with versions and dates released as they are made available.
NOTE: After applying the update to your appliances, physical or virtual, they must be rebooted to fully apply the fix.
Remediation
Install the versions listed below when the releases are made available. We recommend that you install the available fixes. Otherwise, apply any available workarounds.
To remediate this issue, go to the Product Downloads site, and download the applicable product update/hotfix files:
Download and Installation Instructions
For instructions to download product updates and hotfixes, see KB56057 - How to download Enterprise product updates and documentation. Review the Release Notes and Installation Guide for instructions on how to install these updates. All documentation is available at our Product Documentation site.
Frequently Asked Questions (FAQs)
How do I know if my product is vulnerable?
For Endpoint products:
Use the following instructions for endpoint or client-based products:
Use the following instructions for ePO:
Check the version and build of ePO that is installed. For information about how to check the version, see: KB52634.
For Appliances:
Use the following instructions for Appliance-based products:
All Security Bulletins are published on our Knowledge Center. 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 you?
If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability.
How do you 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 of our 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.
We only publish 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.

Scope of this Security Bulletin:
- Any product that we offer that comes bundled with an operating system, either on hardware or as a virtual machine, will be covered in this Security Bulletin.
- Where our software is installed on an operating system provided by the customer, we will 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.
As with previous related CVEs (Spectre/Meltdown variants), we plan to address these vulnerabilities as part of the regular update cycles for the impacted products. These vulnerabilities have been given the code name "ZombieLoad."
For our virtual appliances, including instances running in the cloud, ensure that you have applied the vendor fixes to the virtual environment they are running in.
- CVE-2019-11091
Uncacheable memory on some microprocessors utilizing speculative execution can allow an authenticated user to potentially enable information disclosure via a side channel with local access.

https://access.redhat.com/security/cve/cve-2019-11091
- CVE-2018-12126
Modern Intel® microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub operations. These sub operations allow the processor to hand-off address generation logic into these sub operations for optimized writes. Both of these sub operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer.

https://access.redhat.com/security/cve/cve-2018-12126
- CVE-2018-12130
A flaw was found in the implementation of the "fill buffer," a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution continues speculatively with incorrect data from the fill buffer while the data is fetched from higher-level caches. This response time can be measured to infer data in the fill buffer.

https://access.redhat.com/security/cve/cve-2018-12130
- CVE-2018-12127
Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.
