DEBIAN-CVE-2025-55753

An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0.

An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0. Attempts to renew the certificate then are repeated without delays until it succeeds.  This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66.   Users are recommended to upgrade to version 2.4.66, which fixes the issue.
