CVE-2016-10002 2 Debian, Squid-cache 2 Debian Linux, Squid 2025-04-20 5.0 MEDIUM 7.5 HIGH
Incorrect processing of responses to If-None-Modified HTTP conditional requests in Squid HTTP Proxy 3.1.10 through 3.1.23, 3.2.0.3 through 3.5.22, and 4.0.1 through 4.0.16 leads to client-specific Cookie data being leaked to other clients. Attack requests can easily be crafted by a client to probe a cache for this information.
CVE-2016-10003 1 Squid-cache 1 Squid 2025-04-20 5.0 MEDIUM 7.5 HIGH
Incorrect HTTP Request header comparison in Squid HTTP Proxy 3.5.0.1 through 3.5.22, and 4.0.1 through 4.0.16 results in Collapsed Forwarding feature mistakenly identifying some private responses as being suitable for delivery to multiple clients.
CVE-2022-41318 1 Squid-cache 1 Squid 2025-04-14 N/A 8.6 HIGH
A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7.
CVE-2022-41317 1 Squid-cache 1 Squid 2025-04-14 N/A 6.5 MEDIUM
An issue was discovered in Squid 4.9 through 4.17 and 5.0.6 through 5.6. Due to inconsistent handling of internal URIs, there can be Exposure of Sensitive Information about clients using the proxy via an HTTPS request to an internal cache manager URL. This is fixed in 5.7.
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-2016-4053 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-2016-4555 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-2016-2569 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
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-2014-9749 2 Opensuse, Squid-cache 2 Opensuse, Squid 2025-04-12 4.0 MEDIUM N/A
Squid 3.4.4 through 3.4.11 and 3.5.0.1 through 3.5.1, when Digest authentication is used, allow remote authenticated users to retain access by leveraging a stale nonce, aka "Nonce replay vulnerability."
CVE-2016-2570 1 Squid-cache 1 Squid 2025-04-12 5.0 MEDIUM 7.5 HIGH
The Edge Side Includes (ESI) parser in Squid 3.x before 3.5.15 and 4.x before 4.0.7 does not check buffer limits during XML parsing, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a crafted XML document, related to esi/CustomParser.cc and esi/CustomParser.h.
CVE-2014-7141 1 Squid-cache 1 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 (out-of-bounds read and crash) via a crafted type in an (1) ICMP or (2) ICMP6 packet.
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-2016-3948 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-2016-4054 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 6.8 MEDIUM 8.1 HIGH
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-2016-4051 3 Canonical, Oracle, Squid-cache 3 Ubuntu Linux, Linux, Squid 2025-04-12 6.8 MEDIUM 8.8 HIGH
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-2016-3947 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-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-2014-0128 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.

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-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.
