httpd: CONTINUATION frames DoS

A vulnerability was found in how Apache httpd implements the HTTP/2 protocol. There are insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single stream. This issue could allow an unauthenticated remote attacker to send packets to vulnerable servers,...

AZL-47442 CVE-2024-7246 affecting package grpc for versions less than 1.62.3-1

It's possible for a gRPC client communicating with a HTTP/2 proxy to poison the HPACK table between the proxy and the backend such that other clients see failed requests. It's also possible to use this vulnerability to leak other clients HTTP header keys, but not values. This occurs because the...

varnish: HTTP/2 Broken Window Attack may result in denial of service

A flaw was found in the Varnish cache server, with HTTP/2 support enabled, that may allow a Denial of Service type of attack. A malicious actor can cause the server to run out of credits during the HTTP/2 connection control flow. As a consequence, the server will stop to properly process the acti...

Important: ecs-service-connect-agent

Issue Overview: 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...

Important: tomcat9

Issue Overview: Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This led to a miscounting of active HTTP/2 streams which in turn l...

qtbase: qtbase: Delay any communication until encrypted() can be responded to

A vulnerability was found in Qt where, during a TLS connection for servers supporting HTTP2, Qt may send data to a server even if the TLS certificate doesn't match the redirected address. This occurs because Qt fails to validate the certificate against the redirected address, potentially sending...
