Title:
  cups is intolerant to TLS 1.2

Status in cups package in Ubuntu:
  New

Bug description:
  CUPS 1.7.2-0ubuntu1.7 on Ubuntu Trusty has a security problem where
  connections using TLS 1.2 will fail, forcing a TLS 1.1 retry

  === How to reproduce ====
  1. Connect to the cups server with HTTPS
  2. Check the security info

  or

  1. openssl s_client -connect localhost:631
  2. See the error
  3. openssl s_client -tls1_1 -connect localhost:631
  4. See no error

  TLS 1.1 is not the newest protocol version, and therefore this can be
  considered a security issue.
