Описание
A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further 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. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small.
A flaw was found in the Golang net/http/internal package. This issue may allow a malicious user to send an HTTP request and cause the receiver to read more bytes from network than are in the body (up to 1GiB), causing the receiver to fail reading the response, possibly leading to a Denial of Service (DoS).
