CVE-2023-50269 2 Redhat, Squid-cache 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2025-05-21 8.6 High
Squid is a caching proxy for the Web. Due to an Uncontrolled Recursion bug in versions 2.6 through 2.7.STABLE9, versions 3.1 through 5.9, and versions 6.0.1 through 6.5, Squid may be vulnerable to a Denial of Service attack against HTTP Request parsing. This problem allows a remote client to perform Denial of Service attack by sending a large X-Forwarded-For header when the follow_x_forwarded_for feature is configured. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives.
CVE-2016-10003 1 Squid-cache 1 Squid 2025-04-20 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-2016-10002 3 Debian, Redhat, Squid-cache 3 Debian Linux, Enterprise Linux, Squid 2025-04-20 N/A
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-2022-41318 2 Redhat, Squid-cache 4 Enterprise Linux, Rhel E4s, Rhel Eus and 1 more 2025-04-14 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 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-2016-2571 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 N/A
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-2016-2569 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 N/A
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-2016-2572 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 N/A
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 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 N/A
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-2014-6270 2 Oracle, Squid-cache 2 Solaris, Squid 2025-04-12 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-2016-4555 4 Canonical, Oracle, Redhat and 1 more 4 Ubuntu Linux, Linux, Enterprise Linux and 1 more 2025-04-12 N/A
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-2014-3609 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 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-2016-2390 1 Squid-cache 1 Squid 2025-04-12 N/A
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.
CVE-2016-2570 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2025-04-12 N/A
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-2015-0881 1 Squid-cache 1 Squid 2025-04-12 N/A
