It is, therefore, affected by the following vulnerabilities : - A flaw exists in the modsessioncrypto module due to encryption for data and cookies using the configured ciphers with possibly either...

Design/Logic Flaw

A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0 could be targeted by a malicious peer by having that peer assign priority information for every possible HTTP/2 stream ID. The priority tree would happily continue to store the priority informati...

CVE-2016-6581

A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK...

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...
