CVE-2023-45288

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no...

CVE-2024-27316

HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion...

CVE-2024-30255

Envoy is a cloud-native, open source edge and service proxy. The HTTP/2 protocol stack in Envoy versions prior to 1.29.3, 1.28.2, 1.27.4, and 1.26.8 are vulnerable to CPU exhaustion due to flood of CONTINUATION frames. Envoy's HTTP/2 codec allows the client to send an unlimited number of...

CVE-2024-30255

Envoy's HTTP/2 implementation is vulnerable to CPU exhaustion from a flood of CONTINUATION frames in versions prior to 1.29.3, 1.28.2, 1.27.4, and 1.26.8. The vulnerability lets an attacker send unlimited CONTINUATION frames without END_HEADERS, causing high CPU usage and potential denial of serv...

CVE-2024-27316

CVE-2024-27316 affects the mod_http2 component used with Apache httpd; the issue occurs when HTTP/2 headers exceed the configured limit, causing nghttp2 to buffer headers and potentially leading to memory exhaustion if the client continues sending headers. Connected sources identify affected pack...
