SUSE CVE-2024-2398

When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers for the push surpasses the maximum allowed limit 1000, libcurl aborts the server push. When aborting, libcurl inadvertently does not free all the previously allocated headers and instead lea...

HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RSTSTREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any...

GHSA-RGGV-CV7R-MW98 Connection leaking on idle timeout when TCP congested

Impact If an HTTP/2 connection gets TCP congested, when an idle timeout occurs the HTTP/2 session is marked as closed, and then a GOAWAY frame is queued to be written. However it is not written because the connection is TCP congested. When another idle timeout period elapses, it is then supposed ...

jetty: Improper validation of HTTP/1 content-length

A flaw was found in Jetty that permits a plus sign + preceding the content-length value in a HTTP/1 header field, which is non-standard and more permissive than RFC. This issue could allow an attacker to request smuggling in conjunction with a server that does not close connections after 400...

golang: net/http: handle server errors after sending GOAWAY

A flaw was found in the golang package. In net/http in Go, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if a fatal error preempts the shutdown...
