Advisories for Gem/Net-Ldap package

The Ruby net-ldap gem uses a weak salt when generating SSHA passwords.

Net-ldap does not validate the hostname certificate. Ruby is relying on OpenSSL, and one common mistake made by users of OpenSSL is to assume that OpenSSL will validate the hostname in the server's certificate. did not perform hostname validation. and up contain support for hostname validation, but they still require the user to call a few functions to set it up.
