"This update for squid fixes the following issues :

  - CVE-2016-10003: Prevent incorrect forwarding of cached
    private responses when Collapsed Forwarding feature is
    enabled. This allowed remote attacker (proxy user) to
    discover private and sensitive information about another
    user (bsc#1016169).

  - CVE-2016-10002: Fixed incorrect processing of responses
    to If-None-Modified HTTP conditional requests. This
    allowed responses containing private data to clients it
    should not have reached (bsc#1016168).

  - CVE-2014-9749: Prevent nonce replay in Digest
    authentication, preventing the reuse of stale auth
    tokens (bsc#949942).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
