   - CVE-2015-3455: Squid http proxy configured with client-first SSL bumping
     did not correctly validate server certificate. (bsc#929493)
   - CVE-2016-3948: Fixed denial of service in HTTP Response processing
   - CVE-2016-4051: fixes buffer overflow in cachemgr.cgi (bsc#976553)
   - CVE-2016-4052, CVE-2016-4053, CVE-2016-4054: Fixed multiple issues in
     ESI processing (bsc#976556)

     (CVE-2016-4555, CVE-2016-4556, bsc#979011, bsc#979008)

   Additionally, the following non-security issues have been fixed:

     becoming more popular more CDN servers are producing long lists of IPv6
     and IPv4 addresses. If there are not enough paths selected the IPv4 ones
     may never be reached.
   - squid.init: wait that squid really dies when we kill it on upgrade
     of proclaiming its demise prematurely (bnc#963539)
