NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd-devel package and not the httpd-devel package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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.
