AXSA:2016-464:02 advisory.

    Squid is a high-performance proxy caching server for Web clients,
    supporting FTP, gopher, and HTTP data objects. Unlike traditional
    caching software, Squid handles all requests in a single,
    non-blocking, I/O-driven process. Squid keeps meta data and especially
    hot objects cached in RAM, caches DNS lookups, supports non-blocking
    DNS lookups, and implements negative caching of failed requests.
    Squid consists of a main server program squid, a Domain Name System
    lookup program (dnsserver), a program for retrieving FTP data
    (ftpget), and some management and client tools.
    Security issues fixed with this release:
    CVE-2016-4051
    Buffer overflow in cachemgr.cgi in Squid 2.x, 3.x before 3.5.17, and
    4.x before 4.0.9 might allow remote attackers to cause a denial of
    service or execute arbitrary code by seeding manager reports with
    crafted data.
    CVE-2016-4052
    Multiple stack-based buffer overflows in Squid 3.x before 3.5.17 and
    4.x before 4.0.9 allow remote HTTP servers to cause a denial of
    service or execute arbitrary code via crafted Edge Side Includes (ESI)
    responses.
    CVE-2016-4053
    Squid 3.x before 3.5.17 and 4.x before 4.0.9 allow remote attackers to
    obtain sensitive stack layout information via crafted Edge Side
    Includes (ESI) responses, related to incorrect use of assert and
    compiler optimization.
    CVE-2016-4054
    Buffer overflow in Squid 3.x before 3.5.17 and 4.x before 4.0.9 allows
    remote attackers to execute arbitrary code via crafted Edge Side
    Includes (ESI) responses.
    CVE-2016-4554
    mime_header.cc in Squid before 3.5.18 allows remote attackers to
    bypass intended same-origin restrictions and possibly conduct
    cache-poisoning attacks via a crated HTTP Host header, aka a header
    smuggling issue.
    CVE-2016-4556
    Double free vulnerability in Esi.cc in Squid 3.x before 3.5.18 and 4.x
    before 4.0.10 allows remote servers to cause a denial of service
    (crash) via a crafted Edge Side Includes (ESI) response.
