"From Red Hat Security Advisory 2016:1138 :

An update for squid is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Squid is a high-performance proxy caching server for web clients,
supporting FTP, Gopher, and HTTP data objects.

Security Fix(es) :

* A buffer overflow flaw was found in the way the Squid cachemgr.cgi
utility processed remotely relayed Squid input. When the CGI interface
utility is used, a remote attacker could possibly use this flaw to
execute arbitrary code. (CVE-2016-4051)

* Buffer overflow and input validation flaws were found in the way
Squid processed ESI responses. If Squid was used as a reverse proxy,
or for TLS/ HTTPS interception, a remote attacker able to control ESI
components on an HTTP server could use these flaws to crash Squid,
disclose parts of the stack memory, or possibly execute arbitrary code
as the user running Squid. (CVE-2016-4052, CVE-2016-4053,
CVE-2016-4054)

* An input validation flaw was found in Squid's
mime_get_header_field() function, which is used to search for headers
within HTTP requests. An attacker could send an HTTP request from the
client side with specially crafted header Host header that bypasses
same-origin security protections, causing Squid operating as
interception or reverse-proxy to contact the wrong origin server. It
could also be used for cache poisoning for client not following RFC
7230. (CVE-2016-4554)

* An incorrect reference counting flaw was found in the way Squid
processes ESI responses. If Squid is configured as reverse-proxy, for
TLS/HTTPS interception, an attacker controlling a server accessed by
Squid, could crash the squid worker, causing a Denial of Service
attack. (CVE-2016-4556)"

Red Hat Product Security has rated this update as having a security

high-performance proxy caching server for web clients, supporting FTP,
Gopher, and HTTP data objects. Note that apart from 'squid34', this
version of Red Hat Enterprise Linux also includes the 'squid' packages
which provide Squid version 3.1.

perform cache poisoning attacks on Squid. (CVE-2016-4553)

* A NULL pointer dereference flaw was found in the way Squid processes
ESI responses. If Squid was used as a reverse proxy or for TLS/HTTPS
interception, a malicious server could use this flaw to crash the
Squid worker process. (CVE-2016-4555)

* An incorrect reference counting flaw was found in the way Squid
processes ESI responses. If Squid is configured as reverse-proxy, for
TLS/HTTPS interception, an attacker controlling a server accessed by
Squid, could crash the squid worker, causing a Denial of Service

    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
