漏洞描述
中文描述:

HTTP/2是超文本传输协议的第二版,主要用于保证客户机与服务器之间的通信。 HTTP/2 1.41.0之前版本中存在资源管理错误漏洞。攻击者可借助恶意的客户端构建14,400字节长度的SETTINGS帧利用该漏洞造成拒绝服务。

英文描述:

In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.
