How to fix?

Upgrade SLES:15.0 apache2-devel to version 2.4.33-3.3.1 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:15.0 relevant fixed versions and status.

By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33).
