Allele Security Alert
mod_http2, memory corruption on early pushes
The Apache Software Foundation
Apache HTTP Server
Apache HTTP Server versions 2.4.20 to 2.4.39
Apache HTTP Server version 2.4.41
Proof of concept
HTTP/2 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.
