How to fix?

Upgrade SLES:15.3 apache2-devel to version 2.4.51-150200.3.42.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2-devel package and not the apache2-devel package as distributed by SLES. See How to fix? for SLES:15.3 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.
