Original Publication Date: 07 Dec, 2022
Security Advisory Description
o CVE-2020-14779
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE
(component: Serialization). Supported versions that are affected are Java
SE: 7u271, 8u261, 11.0.8 and 15; Java SE Embedded: 8u261. Difficult to
exploit vulnerability allows unauthenticated attacker with network access
via multiple protocols to compromise Java SE, Java SE Embedded. Successful
attacks of this vulnerability can result in unauthorized ability to cause a
partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note:
Applies to client and server deployment of Java. This vulnerability can be
exploited through sandboxed Java Web Start applications and sandboxed Java
applets. It can also be exploited by supplying data to APIs in the
specified Component without using sandboxed Java Web Start applications or
sandboxed Java applets, such as through a web service. CVSS 3.1 Base Score
3.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/
C:N/I:N/A:L).

Security Advisory Status
F5 Product Development has assigned ID 1188869 (BIG-IP), ID 1188869-1 (BIG-IQ),
and SDC-2129 (Traffix SDC) 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 tables. You can
also use iHealth to diagnose a vulnerability for BIG-IP and BIG-IQ systems. For
more information about using iHealth, refer to K27404821: Using F5 iHealth to
diagnose vulnerabilities. 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

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 that you upgrade to a version with the fix (refer to
the tables).
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
