net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

nodejs: Node.js: Heap-use-after-free in HTTP/2 handling can lead to denial of service

A heap use-after-free vulnerability in the Node.js HTTP/2 component allows a remote attacker to crash the application, causing a denial of service. This is triggered by an unexpected re-entrant call to nghttp2sessionmemsend while nghttp2sessionmemrecv is still executing...

nodejs: Node.js: Remote memory exhaustion via HTTP/2 retained header blocks

A flaw was found in Node.js's handling of HTTP/2. This vulnerability allows a remote attacker to bypass maxSessionMemory limits by sending specially crafted HTTP/2 retained header blocks. This can lead to memory exhaustion, resulting in a denial of service DoS for the affected system...
