DATE CVE VULNERABILITY TITLE RISK
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.

2016-04-19 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.
4.3
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.

7.5
2015-09-28 CVE-2015-5400 Permissions, Privileges, and Access Controls vulnerability in multiple products
Squid before 3.5.6 does not properly handle CONNECT method peer responses when configured with cache_peer, which allows remote attackers to bypass intended restrictions and gain access to a backend proxy via a CONNECT request.
6.8
2015-02-20 CVE-2015-0881 HTTP Header Injection vulnerability in Squid
CRLF injection vulnerability in Squid before 3.1.1 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted header in a response.

2014-09-12 CVE-2014-6270 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
Off-by-one error in the snmpHandleUdp function in snmp_core.cc in Squid 2.x and 3.x, when an SNMP port is configured, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted UDP SNMP request, which triggers a heap-based buffer overflow.
6.8
2011-11-17 CVE-2011-4096 Resource Management Errors vulnerability in Squid-Cache Squid
The idnsGrokReply function in Squid before 3.1.16 does not properly free memory, which allows remote attackers to cause a denial of service (daemon abort) via a DNS reply containing a CNAME record that references another CNAME record that contains an empty A record.
