|---|---|---|---|---|---|---|---|
| CVE-2020-14059 | — | < 3.5.21-26.26.1 | 3.5.21-26.26.1 | Jun 30, 2020 | An issue was discovered in Squid 5.x before 5.0.3. Due to an Incorrect Synchronization, a Denial of Service can occur when processing objects in an SMP cache because of an Ipc::Mem::PageStack::pop ABA problem during access to the memory page/slot management list. | ||
| CVE-2020-11945 | — | < 3.5.21-26.23.1 | 3.5.21-26.23.1 | Apr 23, 2020 | An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code exe | ||
| CVE-2019-12519 | — | < 3.5.21-26.23.1 | 3.5.21-26.23.1 | Apr 15, 2020 | An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evalua | ||
| CVE-2019-12520 | — | < 3.5.21-26.23.1 | 3.5.21-26.23.1 | Apr 15, 2020 | An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the deco | ||
| CVE-2019-12521 | — | < 3.5.21-26.23.1 | 3.5.21-26.23.1 | Apr 15, 2020 | An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the | ||
| CVE-2019-12524 | — | < 3.5.21-26.23.1 | 3.5.21-26.23.1 | Apr 15, 2020 | An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintaine | ||
| CVE-2019-18860 | — | < 3.5.21-26.26.1 | 3.5.21-26.26.1 | Mar 20, 2020 | Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi. | ||
| CVE-2019-12528 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Feb 4, 2020 | 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-2020-8517 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Feb 4, 2020 | 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 bei | ||
| CVE-2020-8450 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Feb 4, 2020 | 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 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Feb 4, 2020 | 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-2019-12526 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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 | ||
| CVE-2019-12523 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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 restric | ||
| CVE-2019-18676 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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 chec | ||
| CVE-2019-18677 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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 | ||
| CVE-2019-18678 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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 | ||
| CVE-2019-18679 | — | < 3.5.21-26.20.1 | 3.5.21-26.20.1 | Nov 26, 2019 | 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. T | ||
| CVE-2019-12529 | — | < 3.5.21-26.17.1 | 3.5.21-26.17.1 | Jul 11, 2019 | 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 | ||
| CVE-2019-12525 | — | < 3.5.21-26.17.1 | 3.5.21-26.17.1 | Jul 11, 2019 | 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.
