CVE-2019-9511 [HIGH] CWE-400 CVE-2019-9511: Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization man Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. De

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.
