   An update that solves 16 vulnerabilities and has two fixes
   is now available.

Description:


   The Squid HTTP proxy has been updated to version 3.3.14, fixing the
   following security issues:

   - Fixed multiple Denial of Service issues in HTTP Response processing.
     (CVE-2016-2569, CVE-2016-2570, CVE-2016-2571, CVE-2016-2572, bsc#968392,
     bsc#968393, bsc#968394, bsc#968395)
   - CVE-2016-3947: Buffer overrun issue in pinger ICMPv6 processing.
     (bsc#973782)
   - CVE-2015-5400: Improper protection of alternate path. (bsc#938715)
   - 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
     (bsc#973783)
   - 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-2016-4553: Fixed cache poisoning issue in HTTP Request handling
     (bsc#979009)
   - CVE-2016-4554: Fixed header smuggling issue in HTTP Request processing
     (bsc#979010)
   - Fixed multiple Denial of Service issues in ESI Response processing.
     (CVE-2016-4555, CVE-2016-4556, bsc#979011, bsc#979008)

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

   - Fix header size in script unsquid.pl. (bsc#902197)
   - Add external helper ext_session_acl to package. (bsc#959290)
   - Update forward_max_tries to permit 25 server paths With cloud sites
     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
     instead
     of proclaiming its demise prematurely (bnc#963539)
