K44030142: OpenSSL vulnerabilities CVE-2022-3786 and CVE-2022-3602
Original Publication Date: 29 Oct, 2022
Latest Publication Date: 10 Nov, 2022
Security Advisory Description
o CVE-2022-3786
A buffer overrun can be triggered in X.509 certificate verification,
specifically in name constraint checking. Note that this occurs after
certificate chain signature verification and requires either a CA to have
signed a malicious certificate or for an application to continue
certificate verification despite failure to construct a path to a trusted
issuer. An attacker can craft a malicious email address in a certificate to
overflow an arbitrary number of bytes containing the `.' character (decimal
46) on the stack. This buffer overflow could result in a crash (causing a
denial of service).
o CVE-2022-3602
A buffer overrun can be triggered in X.509 certificate verification,
specifically in name constraint checking. Note that this occurs after
certificate chain signature verification and requires either a CA to have
signed the malicious certificate or for the application to continue
certificate verification despite failure to construct a path to a trusted
issuer. An attacker can craft a malicious email address to overflow four
attacker-controlled bytes on the stack. This buffer overflow could result
in a crash (causing a denial of service) or potentially remote code
execution.
Note: For more details about CVE-2022-3786 and CVE-2022-3602, refer to OpenSSL
Security Advisory [01 November 2022].
Impact
For products with None in the Versions known to be vulnerable column, there is
no impact.
For products with ** in the various columns, F5 will update this article after
confirming the required information. F5 Support has no additional information
about this issue.
Security Advisory Status
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.
In this section
o BIG-IP and BIG-IQ
o F5OS
o NGINX
o Other products
BIG-IP and BIG-IQ
BIG-IP is Not vulnerable because OpenSSL 3.x is not included in BIG-IP
releases. To see the OpenSSL versions that run on BIG-IP systems, refer to
K11398383: BIG-IP third-party software matrix. If the preceding article does
not apply to your version, follow the links in the article to the third-party
software article for your BIG-IP release.
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.
