Description

The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23, when the Protocols configuration includes h2 or h2c, does not restrict request-header length, which allows remote attackers to cause a denial of service (memory consumption) via crafted CONTINUATION frames in an HTTP/2 request.

Affected configurations

• apache http server 2.4.17 • apache http server 2.4.18 • apache http server 2.4.19 • apache http server 2.4.20 • apache http server 2.4.21 • apache http server 2.4.22 • apache http server 2.4.23
