Descriptions

HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client.

Pushes tempranos de HTTP/2 (versiones 2.4.20 hasta 2.4.39) configurados por ejemplo con "H2PushResource", podrían conllevar a una sobrescritura de memoria en el pushing de grupo de peticiones causando bloqueos. La memoria copiada es la de los valores configurados de encabezado del enlace de inserción, no los datos suministrados por el cliente.

A vulnerability was found in Apache httpd, in mod_http2. Under certain circumstances, HTTP/2 early pushes could lead to memory corruption, causing a server to crash.
