Important: golang

Issue Overview:

HTTP and MIME header parsing could allocate large amounts of memory, even when parsing small inputs.

Certain unusual patterns of input data could cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service.
