| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Go http2 package (affected versions not specified)
Description
A malicious HTTP/2 client can cause excessive server resource consumption by rapidly creating requests and immediately resetting them. This allows the attacker to create a new request while the existing one is still executing, despite the total number of requests being bounded by the
http2.Server.MaxConcurrentStreams setting. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit. New requests arriving when at the limit will be queued until a handler exits, and if the request queue grows too large, the server will terminate the connection.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
