How to fix?

Upgrade Oracle:8 httpd-devel to version 0:2.4.37-21.0.1.module+el8.2.0+5576+c083ffcb or higher.
This issue was patched in ELSA-2020-3714.

NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd-devel package and not the httpd-devel package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.
