How to fix?

Upgrade Ubuntu:22.10 apache2 to version 2.4.54-2ubuntu1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2 package and not the apache2 package as distributed by Ubuntu. See How to fix? for Ubuntu:22.10 relevant fixed versions and status.

Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected.
