2016-05-10 CVE-2016-4554 Insufficient Verification of Data Authenticity vulnerability in multiple products
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 crafted HTTP Host header, aka a "header smuggling" issue.

2016-05-10 CVE-2016-4553 Insufficient Verification of Data Authenticity vulnerability in multiple products
client_side.cc in Squid before 3.5.18 and 4.x before 4.0.10 does not properly ignore the Host header when absolute-URI is provided, which allows remote attackers to conduct cache-poisoning attacks via an HTTP request.

2016-04-25 CVE-2016-4051 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
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.

2016-04-19 CVE-2016-2390 Improper Input Validation vulnerability in Squid-Cache Squid
The FwdState::connectedToPeer method in FwdState.cc in Squid before 3.5.14 and 4.0.x before 4.0.6 does not properly handle SSL handshake errors when built with the --with-openssl option, which allows remote attackers to cause a denial of service (application crash) via a plaintext HTTP message.

2016-04-07 CVE-2016-3947 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Heap-based buffer overflow in the Icmp6::Recv function in icmp/Icmp6.cc in the pinger utility in Squid before 3.5.16 and 4.x before 4.0.8 allows remote servers to cause a denial of service (performance degradation or transition failures) or write sensitive information to log files via an ICMPv6 packet.
