TITLE

HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion

DESCRIPTION

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. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service (DoS) attacks. Apple SwiftNIO Used in products such as HTTP/2 Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. HTTP/2 is the second version of the hypertext transfer protocol, which is mainly used to ensure the communication between the client and the server. A resource management error vulnerability exists in HTTP/2. For the stable distribution (buster), these problems have been fixed in version 10.19.0~dfsg1-1. We recommend that you upgrade your nodejs packages.
