  Cups SSL is vulernable to POODLE

Status in cups package in Ubuntu:
  Fix Released
Status in cups source package in Trusty:

Bug description:

   * Cups in Trusty is vulnerbable to the Poodle SSLv3. This disables it by default.
   * Users who have clients that don't support TLS1.0 will not be able to connect, unless
   they specify the additional options in cupsd.conf.

  [Test Case]

   * Install cupsd with /etc/cups/cupsd.conf SSL options SSLPort 443 and SSLOptions None
     * This should show up as having RC4 and SSLv3 disabled via a test like ssllabs.
   * Same but specify SSLOptions to AllowSSL3 or AllowRC4.

  [Regression Potential]

   * One assumption was this should only affect WinXP and even then only
  IE6 winxp users.  If incorrect more could be affected.

   * The biggest issue could be that AllowSSL3 or AllowRC4 don't work in
  some unknown corner case.  There's no evidence of this and other
  distros have deployed a very similar patch.

  [Other Info]

   * Only targetting 14.04 because of my assumption that if you're on
  12.04 you are more likely to have older clients connecting to it.

  Original description:

  On 12.04 and 14.04 if you enable cups ssl you are vulnerable to
  poodle, and there does not appear to be any way to mitigate it in Cups

  Ubuntu 14.04 - https://www.ssllabs.com/ssltest/analyze.html?d=
  Ubuntu 12.04 - https://www.ssllabs.com/ssltest/analyze.html?d=

  Fixed in wily - https://www.ssllabs.com/ssltest/analyze.html?d=
  Upstream fix - https://www.cups.org/str.php?L4476

  Should we disable ssvl3 in the 12.04/14.04 cups by default and
  backport the option to turn it back on?
