NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd:2.4/mod_md package and not the httpd:2.4/mod_md package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
