UBUNTU-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...

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...

CVE-2019-12526

CVE-2019-12526 affects Squid prior to 4.9, where URN response handling can overflow the heap with attacker-controlled data when processing URN responses from a remote server. The connected advisories confirm that a fix is available in newer upstream versions (e.g., 4.10+ as reflected in ALT Linux...

CVE-2019-12523

CVE-2019-12523 affects Squid prior to 4.9, where handling a URN request transforms it into an HTTP request that bypasses the standard incoming HTTP access checks. This allows an attacker to access restricted HTTP servers (e.g., localhost) by bypassing ACLs via the URN path, with potential exposur...

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,...

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...

CVE-2019-18676

CVE-2019-18676 affects Squid 3.x and 4.x up to 4.8, where incorrect input validation enables a heap-based buffer overflow that can cause a Denial of Service to all clients using the proxy. The connected advisories describe the issue scope and related CVEs in the same Squid codebase (URn/URI proce...

CVE-2019-18677

CVE-2019-18677 affects Squid 3.x and 4.x up to 4.8 where the append_domain setting can cause improper message processing, leading to traffic being redirected to origins that should not be delivered to. This is confirmed in multiple advisories (e.g., ALAS2-2023-2318) listing CVE-2019-18677 as a se...

CVE-2019-18677

An issue was discovered in Squid 3.x and 4.x through 4.8 when the appenddomain 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...

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-controlle...

CVE-2019-18678

CVE-2019-18678 affects Squid 3.x and 4.x up to 4.8. It arises from a request header with whitespace between a header name and a colon, enabling an attacker to smuggle HTTP requests through frontend software to a Squid instance. The resulting Response messages corrupt caches between the client and...
