CVE-2016-6580

CVE-2016-6580 affects HTTP/2 implementations built with the Python priority library older than 1.2.0. The vulnerability arises when a peer can assign priority information for every HTTP/2 stream ID, allowing the priority data structure to grow without bound, consuming memory and driving extremely...
