"The Squid HTTP proxy has been updated to version 3.3.14, fixing the

    (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)

    multiple issues in ESI processing (bsc#976556)

  - 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 :

  - 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
