| CVE-2023-50269 | 1 Squid-cache | 1 Squid | 2024-11-21 | N/A | 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-2023-49288 | 1 Squid-cache | 1 Squid | 2024-11-21 | N/A | 8.6 HIGH |
| Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Affected versions of squid are subject to a a Use-After-Free bug which can lead to a Denial of Service attack via collapsed forwarding. All versions of Squid from 3.5 up to and including 5.9 configured with "collapsed_forwarding on" are vulnerable. Configurations with "collapsed_forwarding off" or without a "collapsed_forwarding" directive are not vulnerable. This bug is fixed by Squid version 6.0.1. Users are advised to upgrade. Users unable to upgrade should remove all collapsed_forwarding lines from their squid.conf. | |||||

| Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to an Incorrect Check of Function Return Value bug Squid is vulnerable to a Denial of Service attack against its Helper process management. This bug is fixed by Squid version 6.5. Users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
| CVE-2023-49285 | 1 Squid-cache | 1 Squid | 2024-11-21 | N/A | 8.6 HIGH |
| Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a Buffer Overread bug Squid is vulnerable to a Denial of Service attack against Squid HTTP Message processing. This bug is fixed by Squid version 6.5. Users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
| CVE-2023-46848 | 2 Redhat, Squid-cache | 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more | 2024-11-21 | N/A | 8.6 HIGH |
| Squid is vulnerable to Denial of Service, where a remote attacker can perform DoS by sending ftp:// URLs in HTTP Request messages or constructing ftp:// URLs from FTP Native input. | |||||
| CVE-2023-46847 | 2 Redhat, Squid-cache | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 7 more | 2024-11-21 | N/A | 8.6 HIGH |
| Squid is vulnerable to a Denial of Service, where a remote attacker can perform buffer overflow attack by writing up to 2 MB of arbitrary data to heap memory when Squid is configured to accept HTTP Digest Authentication. | |||||
| CVE-2021-46784 | 2 Debian, Squid-cache | 2 Debian Linux, Squid | 2024-11-21 | N/A | 6.5 MEDIUM |
| In Squid 3.x through 3.5.28, 4.x through 4.17, and 5.x before 5.6, due to improper buffer management, a Denial of Service can occur when processing long Gopher server responses. | |||||
| CVE-2021-41611 | 2 Fedoraproject, Squid-cache | 2 Fedora, Squid | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote server to obtain security trust well improperly. This indication of trust may be passed along to clients, allowing access to unsafe or hijacked services. | |||||
| CVE-2021-33620 | 3 Debian, Fedoraproject, Squid-cache | 3 Debian Linux, Fedora, Squid | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| Squid before 4.15 and 5.x before 5.0.6 allows remote servers to cause a denial of service (affecting availability to all clients) via an HTTP response. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent by the server. | |||||
| CVE-2021-31808 | 4 Debian, Fedoraproject, Netapp and 1 more | 4 Debian Linux, Fedora, Cloud Manager and 1 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this. | |||||
| CVE-2021-31807 | 3 Fedoraproject, Netapp, Squid-cache | 3 Fedora, Cloud Manager, Squid | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. An integer overflow problem allows a remote server to achieve Denial of Service when delivering responses to HTTP Range requests. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent. | |||||
| CVE-2021-31806 | 4 Debian, Fedoraproject, Netapp and 1 more | 4 Debian Linux, Fedora, Cloud Manager and 1 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request processing. | |||||
| CVE-2021-28662 | 3 Debian, Fedoraproject, Squid-cache | 3 Debian Linux, Fedora, Squid | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic. | |||||
| CVE-2021-28652 | 3 Debian, Fedoraproject, Squid-cache | 3 Debian Linux, Fedora, Squid | 2024-11-21 | 4.0 MEDIUM | 4.9 MEDIUM |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege. | |||||
| CVE-2021-28651 | 4 Debian, Fedoraproject, Netapp and 1 more | 4 Debian Linux, Fedora, Cloud Manager and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption. | |||||
| CVE-2021-28116 | 3 Debian, Fedoraproject, Squid-cache | 3 Debian Linux, Fedora, Squid | 2024-11-21 | 4.3 MEDIUM | 3.7 LOW |
| Squid through 4.14 and 5.x through 5.0.5, in some configurations, allows information disclosure because of an out-of-bounds read in WCCP protocol data. This can be leveraged as part of a chain for remote code execution as nobody. | |||||
| CVE-2020-8517 | 3 Canonical, Opensuse, Squid-cache | 3 Ubuntu Linux, Leap, Squid | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy. | |||||
| CVE-2020-8450 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 7.5 HIGH | 7.3 HIGH |
| An issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can cause a buffer overflow in a Squid instance acting as a reverse proxy. | |||||
| CVE-2020-8449 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters. | |||||
