K41043270: Intel processor vulnerabilities CVE-2021-0086 and CVE-2021-0089

Original Publication Date: 09 Sep, 2021

Security Advisory Description

o CVE-2021-0086

    Observable response discrepancy in floating-point operations for some Intel
    (R) Processors may allow an authorized user to potentially enable
    information disclosure via local access.

  o CVE-2021-0089

    Observable response discrepancy in some Intel(R) Processors may allow an
    authorized user to potentially enable information disclosure via local
    access.

Impact

All versions of Virtual Edition (VE) for the BIG-IP and BIG-IQ products are
potentially impacted if the processors underlying the VE installations
are affected. Microcode updates from Intel are available to address this issue
but must be applied at the hardware level, which is outside the scope of the
ability of F5 to support or patch.

This hardware issue impacts all the BIG-IP, BIG-IQ, VIPRION, and VELOS
platforms using the following Intel Xeon processor families:

  o Ivy Bridge EP
  o Sandy Bridge EP

Security Advisory Status

F5 Product Development has assigned IDs 1031389 and 1031397 (BIG-IP and F5OS)
and IDs 1035373 and 1035377 (BIG-IQ) to this vulnerability.

To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases, point releases, or
hotfixes that address the vulnerability, refer to the following table. For more
information about security advisory versioning, refer to K51812227:
Understanding security advisory versioning.

Note: After a fix is introduced for a given minor branch, that fix applies to
all subsequent maintenance and point releases for that branch, and no
additional fixes for that branch will be listed in the table. For example, when
a fix is introduced in 14.1.2.3, the fix also applies to 14.1.2.4, and all
later 14.1.x releases (14.1.3.x., 14.1.4.x). For more information, refer to
K51812227: Understanding security advisory versioning. Additionally, software
versions preceding those listed in the following table have reached the End of
Technical Support (EoTS) phase of their lifecycle and are no longer evaluated
for security issues. For more information, refer to the Security hotfixes
section of K4602: Overview of the F5 security vulnerability response policy.

^1F5 evaluates only software versions that have not yet reached the End of
Technical Support (EoTS) phase of their lifecycle.

^2The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

For the supported BIG-IP and BIG-IQ software versions for the F5 hardware
platforms, refer to K9476: The F5 hardware/software compatibility matrix.

Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by installing a version listed in
the Fixes introduced in column. If the Fixes introduced in column does not list
a version for your branch, then no update candidate currently exists for that
branch and F5 recommends upgrading to a version with the fix (refer to the
table).

If the Fixes introduced in column lists a version prior to the one you are
running, in the same branch, then your version should have the fix.

Mitigation

None
