Use CVE-2015-5381.

Use CVE-2015-5382. For 1.1, the security fix for _alt seems to be
announced in http://trac.roundcube.net/changeset/e84fafcec/github --
do you mean that part of the _alt vulnerability was fixed in
http://trac.roundcube.net/changeset/681ba6fc3/github and then a
different part of the _alt vulnerability was fixed in
http://trac.roundcube.net/changeset/e84fafcec/github (if so, then
there would potentially be another CVE ID)?

>> Add .htaccess files to deny access to config, temp, logs

Use CVE-2015-5383. Note that
http://trac.roundcube.net/browser/github/INSTALL states:

  REQUIREMENTS
  * .htaccess support allowing overrides for DirectoryIndex

Thus, we wouldn't want to have a separate CVE ID for a scenario in
which someone attempts to use Roundcube with nginx.
