with AllowEncodedSlashes On and MergeSlashes Off allows to potentially leak NTLM
hashes to a malicious server via SSRF and malicious requests or content
Users are recommended to upgrade to version 2.4.66, which fixes the issue.

- CWE-190 - Integer Overflow or Wraparound
Summary
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.
