Advisories for Npm/Https-Proxy-Agent package

Versions of https-proxy-agent prior to 2.2.3 are vulnerable to Machine-In-The-Middle. The package fails to enforce TLS on the socket if the proxy server responds the to the request with a HTTP status different than 200. This allows an attacker with access to the proxy server to intercept unencrypted communications, which may include sensitive information such as credentials. Recommendation Upgrade to version 3.0.0 or 2.2.3.

https-proxy-agent passes auth option to the Buffer constructor without proper sanitization, resulting in DoS and uninitialized memory leak in setups where an attacker could submit typed input to the auth parameter (e.g. JSON).
