CVE-2019-9513 [HIGH] CWE-400 CVE-2019-9513: Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of ser Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

CVE-2019-9512 [HIGH] CWE-400 CVE-2019-9512: Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of servic Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

CVE-2019-9518 [HIGH] CWE-400 CVE-2019-9518: Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a deni Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandw

CVE-2019-9516 [MEDIUM] CWE-400 CVE-2019-9516: Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of serv Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the
