Description Pedro Sampaio 2018-03-26 15:24:40 UTC 
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
vulnerabilty 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.

Versions Affected:
httpd 2.4.17 to 2.4.29
