| CVE-2024-23638 | 2 Redhat, Squid-cache | 2 Enterprise Linux, Squid | 2025-06-17 | 6.5 Medium |
| Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6 is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. 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. As a workaround, prevent access to Cache Manager using Squid's main access control: `http_access deny manager`. | ||||
| 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-2015-0881 | 1 Squid-cache | 1 Squid | 2025-04-12 | 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-2016-4553 | 4 Canonical, Oracle, Redhat and 1 more | 4 Ubuntu Linux, Linux, Enterprise Linux and 1 more | 2025-04-12 | N/A |
| 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-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-2016-4052 | 3 Canonical, Redhat, Squid-cache | 3 Ubuntu Linux, Enterprise Linux, Squid | 2025-04-12 | N/A |
| 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-2016-3948 | 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-2014-3609 | 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." | ||||

| 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-2014-9749 | 2 Opensuse, Squid-cache | 2 Opensuse, Squid | 2025-04-12 | 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." | ||||
