CVE-2023-43622
Apache HTTP Server: DoS in HTTP/2 with initial windows size 0
Résumé
Apache HTTP Server: DoS in HTTP/2 with initial windows size 0
Description d'origine
La description telle que publiée par la source (souvent en anglais).
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.
Users are recommended to upgrade to version 2.4.58, which fixes the issue.
