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-2016-4556 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
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.

Squid 3.x before 3.5.15 and 4.x before 4.0.7 does not properly append data to String objects, which allows remote servers to cause a denial of service (assertion failure and daemon exit) via a long string, as demonstrated by a crafted HTTP Vary header.
CVE-2016-4555 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
client_side_request.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 crafted Edge Side Includes (ESI) responses.
CVE-2016-4554 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 5.0 MEDIUM 8.6 HIGH
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.
CVE-2016-4053 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 4.3 MEDIUM 3.7 LOW
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-2016-3947 2 Canonical, Squid-cache 2 Ubuntu Linux, Squid 2025-04-12 7.5 HIGH 8.2 HIGH
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.
CVE-2015-0881 1 Squid-cache 1 Squid 2025-04-12 4.3 MEDIUM N/A
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.
CVE-2014-6270 2 Oracle, Squid-cache 2 Solaris, Squid 2025-04-12 6.8 MEDIUM N/A
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.
CVE-2016-2572 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
http.cc in Squid 4.x before 4.0.7 relies on the HTTP status code after a response-parsing failure, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a malformed response.
CVE-2016-3948 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
Squid 3.x before 3.5.16 and 4.x before 4.0.8 improperly perform bounds checking, which allows remote attackers to cause a denial of service via a crafted HTTP response, related to Vary headers.
CVE-2014-0128 2 Opensuse, Squid-cache 2 Opensuse, Squid 2025-04-12 5.0 MEDIUM N/A
Squid 3.1 before 3.3.12 and 3.4 before 3.4.4, when SSL-Bump is enabled, allows remote attackers to cause a denial of service (assertion failure) via a crafted range request, related to state management.
CVE-2016-2571 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
http.cc in Squid 3.x before 3.5.15 and 4.x before 4.0.7 proceeds with the storage of certain data after a response-parsing failure, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a malformed response.
CVE-2015-5400 3 Debian, Fedoraproject, Squid-cache 3 Debian Linux, Fedora, Squid 2025-04-12 6.8 MEDIUM N/A
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.
CVE-2016-4553 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 5.0 MEDIUM 8.6 HIGH
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.
CVE-2014-3609 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM N/A
HttpHdrRange.cc in Squid 3.x before 3.3.12 and 3.4.x before 3.4.6 allows remote attackers to cause a denial of service (crash) via a request with crafted "Range headers with unidentifiable byte-range values."
CVE-2014-7142 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Solaris, Squid 2025-04-12 6.4 MEDIUM N/A
The pinger in Squid 3.x before 3.4.8 allows remote attackers to obtain sensitive information or cause a denial of service (crash) via a crafted (1) ICMP or (2) ICMP6 packet size.
CVE-2012-5643 1 Squid-cache 1 Squid 2025-04-11 5.0 MEDIUM N/A
Multiple memory leaks in tools/cachemgr.cc in cachemgr.cgi in Squid 2.x and 3.x before 3.1.22, 3.2.x before 3.2.4, and 3.3.x before 3.3.0.2 allow remote attackers to cause a denial of service (memory consumption) via (1) invalid Content-Length headers, (2) long POST requests, or (3) crafted authentication credentials.
CVE-2011-3205 1 Squid-cache 1 Squid 2025-04-11 6.8 MEDIUM N/A
Buffer overflow in the gopherToHTML function in gopher.cc in the Gopher reply parser in Squid 3.0 before 3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11 allows remote Gopher servers to cause a denial of service (memory corruption and daemon restart) or possibly have unspecified other impact via a long line in a response. NOTE: This issue exists because of a CVE-2005-0094 regression.
