From: Stefan Eissing <icing () apache org>
Date: Mon, 14 Mar 2022 10:07:40 +0000

Severity: low

Description:

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.
