2019-08-15 CVE-2019-12854 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. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 7.5
2019-11-26 CVE-2019-12523 An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 9.1
2019-11-26 CVE-2019-12526 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. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 9.8
2019-11-26 CVE-2019-18676 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. Ubuntu_linux, Debian_linux, Fedora, Squid 7.5
2019-11-26 CVE-2019-18677 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. Ubuntu_linux, Fedora, Squid 6.1
2019-11-26 CVE-2019-18678 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... Ubuntu_linux, Debian_linux, Fedora, Squid 5.3
2019-11-26 CVE-2019-18679 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. Ubuntu_linux, Debian_linux, Fedora, Squid 7.5
2020-02-04 CVE-2020-8449 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. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 7.5
2020-02-04 CVE-2020-8450 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. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 7.3
2020-02-04 CVE-2019-12528 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. Ubuntu_linux, Debian_linux, Fedora, Leap, Squid 7.5
