When an HTTP/2 stream was destroyed after being handled, the Apache HTTP
Server prior to version 2.4.30 could have written a NULL pointer
potentially to an already freed memory. The memory pools maintained by the
server make this vulnerability hard to trigger in usual configurations, the
reporter and the team could not reproduce it outside debug builds, so it is
classified as low risk.

mdeslaur | artful and older don’t enable http2 in the build. this needs to be fixed by backporting the whole http2 module from a more-recent apache2 |
