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.

If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier.
