go -- multiple vulnerabilities

The Go project reports:

path/filepath: path traversal in filepath.Clean on Windows

On Windows, the filepath.Clean function could transform an invalid path such as a/../c:/b into the valid path c:\b. This transformation of a relative (if invalid) path into an absolute path could enable a directory traversal attack. The filepath.Clean function will now transform this path into the relative (but still invalid) path .\c:\b.

net/http: avoid quadratic complexity in HPACK decoding

A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.
