| CVE-2019-12526 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap. | |||||
| CVE-2019-18677 | 3 Canonical, Fedoraproject, Squid-cache | 3 Ubuntu Linux, Fedora, Squid | 2023-12-10 | 5.8 MEDIUM | 6.1 MEDIUM |
| An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to. | |||||
| CVE-2019-18678 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-12-10 | 5.0 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon. | |||||
| CVE-2020-8450 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 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-2019-18679 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks. | |||||
| CVE-2020-8517 | 3 Canonical, Opensuse, Squid-cache | 3 Ubuntu Linux, Leap, Squid | 2023-12-10 | 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-2019-12528 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes. | |||||
| CVE-2020-8449 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 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. | |||||
| CVE-2019-18676 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme. | |||||
| CVE-2019-12854 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memory. On systems with memory access protections, this can cause the CGI process to terminate unexpectedly, resulting in a denial of service for all clients using it. | |||||
| CVE-2019-12529 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages. | |||||
| CVE-2019-13345 | 2 Debian, Squid-cache | 2 Debian Linux, Squid | 2023-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| The cachemgr.cgi web module of Squid through 4.7 has XSS via the user_name or auth parameter. | |||||
| CVE-2019-12527 | 5 Canonical, Debian, Fedoraproject and 2 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2023-12-10 | 6.8 MEDIUM | 8.8 HIGH |
| An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data. | |||||
| CVE-2019-12525 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1. | |||||
| CVE-2018-19131 | 1 Squid-cache | 1 Squid | 2023-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| Squid before 4.4 has XSS via a crafted X.509 certificate during HTTP(S) error page generation for certificate errors. | |||||
| CVE-2018-19132 | 2 Debian, Squid-cache | 2 Debian Linux, Squid | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| Squid before 4.4, when SNMP is enabled, allows a denial of service (Memory Leak) via an SNMP packet. | |||||
