CVE-2024-28182 Reading unbounded number of HTTP/2 CONTINUATION frames to cause excessive CPU usage

nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK...

CVE-2024-27919 HTTP/2: memory exhaustion due to CONTINUATION frame flood

Envoy is a cloud-native, open-source edge and service proxy. In versions 1.29.0 and 1.29.1, theEnvoy HTTP/2 protocol stack is vulnerable to the flood of CONTINUATION frames. Envoy's HTTP/2 codec does not reset a request when header map limits have been exceeded. This allows an attacker to send an...

New HTTP/2 Vulnerability Exposes Web Servers to DoS Attacks

New research has found that the CONTINUATION frame in the HTTP/2 protocol can be exploited to conduct denial-of-service DoS attacks. The technique has been codenamed HTTP/2 CONTINUATION Flood by security researcher Bartek Nowotarski, who reported the issue to the CERT Coordination Center CERT/CC ...

Denial Of Service (DoS)

amphp/http-client is vulnerable to Denial Of Service. The vulnerability is due to unbounded buffering of HTTP/2 CONTINUATION frames until the ENDHEADERS flag is received, which results in a memory exhaustion crash...

CVE-2024-27316: Allocation of Resources Without Limits or Throttling

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: Detection of Error Condition Without Action

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...
