- Update to 2.4.58:
  *) SECURITY: CVE-2023-45802: Apache HTTP Server: HTTP/2 stream
     memory not reclaimed right away on RST (cve.mitre.org)
     When a HTTP/2 stream was reset (RST frame) by a client, there
     was a time window were the request's memory resources were not
     reclaimed immediately. Instead, de-allocation was deferred to
     connection close. A client could send new requests and resets,
     keeping the connection busy and open and causing the memory
     footprint to keep on growing. On connection close, all resources
     were reclaimed, but the process might run out of memory before
     that.
     This was found by the reporter during testing of CVE-2023-44487
     (HTTP/2 Rapid Reset Exploit) with their own test client. During
     "normal" HTTP/2 use, the probability to hit this bug is very
     low. The kept memory would not become noticeable before the
     connection closes or times out.
     Users are recommended to upgrade to version 2.4.58, which fixes
     the issue.

  *) SECURITY: CVE-2023-43622: Apache HTTP Server: DoS in HTTP/2 with
     initial windows size 0 (cve.mitre.org)
     An attacker, opening a HTTP/2 connection with an initial window
     size of 0, was able to block handling of that connection
     indefinitely in Apache HTTP Server. This could be used to
     exhaust worker resources in the server, similar to the well
     known "slow loris" attack pattern.
     This has been fixed in version 2.4.58, so that such connection
     are terminated properly after the configured connection timeout.
     This issue affects Apache HTTP Server: from 2.4.55 through
     2.4.57.
