CVE-2022-29167

Hawk is an HTTP authentication scheme providing mechanisms for making
authenticated HTTP requests with partial cryptographic verification of the
request and response, covering the HTTP method, request URI, host, and
optionally the request payload. Hawk used a regular expression to parse
Host HTTP header (Hawk.utils.parseHost()), which was subject to regular
expression DoS attack - meaning each added character in the attacker’s
input increases the computation time exponentially. parseHost() was
patched in 9.0.1 to use built-in URL class to parse hostname instead.
Hawk.authenticate() accepts options argument. If that contains host
and port, those would be used instead of a call to utils.parseHost().
