K000139225: nghttp2 vulnerability CVE-2024-28182
Published Date: Apr 10, 2024
Security Advisory Description
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C.
The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number
of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK
context in sync. This causes excessive CPU usage to decode HPACK stream.
nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of
CONTINUATION frames it accepts per stream. There is no workaround for this
vulnerability. (CVE-2024-28182)
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 is still researching the issue
and 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 Evaluated products 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 20.0.2, the fix also applies to 20.0.3, and all later
20.1.x releases. For more information, refer to K51812227: Understanding
