github.com/golang/go is vulnerable to Denial Of Service (DoS). The vulnerability exists because the readChunkLine
function in chunked.go
does not properly check the bytes from the request or response body. A malicious attacker can exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. This may lead to an application crash by inserting large metadata segments within the HTTP header.
