"  - mod_nss-CVE-2013-4566-NSSVerifyClient.diff fixes
    CVE-2013-4566: If 'NSSVerifyClient none' is set in the
    server / vhost context (i.e. when server is configured
    to not request or require client certificate
    authentication on the initial connection), and client
    certificate authentication is expected to be required
    for a specific directory via 'NSSVerifyClient require'
    setting, mod_nss fails to properly require certificate
    authentication. Remote attacker can use this to access
    content of the restricted directories. [bnc#853039]

  - glue documentation added to
    /etc/apache2/conf.d/mod_nss.conf :

  - simultaneaous usage of mod_ssl and mod_nss

  - SNI concurrency

  - SUSE framework for apache configuration, Listen
    directive

  - module initialization

  - mod_nss-conf.patch obsoleted by scratch-version of
    nss.conf.in or mod_nss.conf, respectively. This also
    leads to the removal of nss.conf.in specific chunks in
    mod_nss-negotiate.patch and mod_nss-tlsv1_1.patch .

  - mod_nss_migrate.pl conversion script added; not patched
    from source, but partially rewritten.

  - README-SUSE.txt added with step-by-step instructions on
    how to convert and manage certificates and keys, as well
    as a rationale about why mod_nss was included in SLES.

  - package ready for submission [bnc#847216]

  - generic cleanup of the package :

  - explicit Requires: to mozilla-nss >= 3.15.1, as TLS-1.2
    support came with this version - this is the objective
    behind this version update of apache2-mod_nss. Tracker
    bug [bnc#847216]

  - change path /etc/apache2/alias to /etc/apache2/mod_nss.d
    to avoid ambiguously interpreted name of directory.

  - merge content of /etc/apache2/alias to
    /etc/apache2/mod_nss.d if /etc/apache2/alias exists.

  - set explicit filemodes 640 for %post generated *.db
    files in /etc/apache2/mod_nss.d"
