CVE-2013-0189 2 Canonical, Squid-cache 2 Ubuntu Linux, Squid 2024-11-21 5.0 MEDIUM N/A
cachemgr.cgi in Squid 3.1.x and 3.2.x, possibly 3.1.22, 3.2.4, and other versions, allows remote attackers to cause a denial of service (resource consumption) via a crafted request. NOTE: this issue is due to an incorrect fix for CVE-2012-5643, possibly involving an incorrect order of arguments or incorrect comparison.
CVE-2012-5643 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
Multiple memory leaks in tools/cachemgr.cc in cachemgr.cgi in Squid 2.x and 3.x before 3.1.22, 3.2.x before 3.2.4, and 3.3.x before 3.3.0.2 allow remote attackers to cause a denial of service (memory consumption) via (1) invalid Content-Length headers, (2) long POST requests, or (3) crafted authentication credentials.
CVE-2012-2213 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
Squid 3.1.9 allows remote attackers to bypass the access configuration for the CONNECT method by providing an arbitrary allowed hostname in the Host HTTP header. NOTE: this issue might not be reproducible, because the researcher is unable to provide a squid.conf file for a vulnerable system, and the observed behavior is consistent with a squid.conf file that was (perhaps inadvertently) designed to allow access based on a "req_header Host" acl regex that matches www.uol.com.br
CVE-2011-4096 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
The idnsGrokReply function in Squid before 3.1.16 does not properly free memory, which allows remote attackers to cause a denial of service (daemon abort) via a DNS reply containing a CNAME record that references another CNAME record that contains an empty A record.
CVE-2011-3205 1 Squid-cache 1 Squid 2024-11-21 6.8 MEDIUM N/A
Buffer overflow in the gopherToHTML function in gopher.cc in the Gopher reply parser in Squid 3.0 before 3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11 allows remote Gopher servers to cause a denial of service (memory corruption and daemon restart) or possibly have unspecified other impact via a long line in a response. NOTE: This issue exists because of a CVE-2005-0094 regression.
CVE-2010-3072 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
The string-comparison functions in String.cci in Squid 3.x before 3.1.8 and 3.2.x before 3.2.0.2 allow remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request.
CVE-2010-2951 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
dns_internal.cc in Squid 3.1.6, when IPv6 DNS resolution is not enabled, accesses an invalid socket during an IPv4 TCP DNS query, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via vectors that trigger an IPv4 DNS response with the TC bit set.
CVE-2010-0639 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
The htcpHandleTstRequest function in htcp.c in Squid 2.x before 2.6.STABLE24 and 2.7 before 2.7.STABLE8, and htcp.cc in 3.0 before 3.0.STABLE24, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets to the HTCP port.
CVE-2010-0308 1 Squid-cache 1 Squid 2024-11-21 4.0 MEDIUM N/A
lib/rfc1035.c in Squid 2.x, 3.0 through 3.0.STABLE22, and 3.1 through 3.1.0.15 allows remote attackers to cause a denial of service (assertion failure) via a crafted DNS packet that only contains a header.
CVE-2009-2855 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
The strListGetItem function in src/HttpHeaderTools.c in Squid 2.7 allows remote attackers to cause a denial of service via a crafted auth header with certain comma delimiters that trigger an infinite loop of calls to the strcspn function.
CVE-2009-2622 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
Squid 3.0 through 3.0.STABLE16 and 3.1 through 3.1.0.11 allows remote attackers to cause a denial of service via malformed requests including (1) "missing or mismatched protocol identifier," (2) missing or negative status value," (3) "missing version," or (4) "missing or invalid status number," related to (a) HttpMsg.cc and (b) HttpReply.cc.
CVE-2009-2621 1 Squid-cache 1 Squid 2024-11-21 5.0 MEDIUM N/A
Squid 3.0 through 3.0.STABLE16 and 3.1 through 3.1.0.11 does not properly enforce "buffer limits and related bound checks," which allows remote attackers to cause a denial of service via (1) an incomplete request or (2) a request with a large header size, related to (a) HttpMsg.cc and (b) client_side.cc.
CVE-2005-0211 2 Debian, Squid-cache 2 Debian Linux, Squid 2024-11-20 7.5 HIGH N/A
Buffer overflow in wccp.c in Squid 2.5 before 2.5.STABLE7 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long WCCP packet, which is processed by a recvfrom function call that uses an incorrect length parameter.
CVE-2024-45802 1 Squid-cache 1 Squid 2024-11-05 N/A 7.5 HIGH
Squid is an open source caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to Input Validation, Premature Release of Resource During Expected Lifetime, and Missing Release of Resource after Effective Lifetime bugs, Squid is vulnerable to Denial of Service attacks by a trusted server against all clients using the proxy. This bug is fixed in the default build configuration of Squid version 6.10.
CVE-2023-5824 2 Redhat, Squid-cache 2 Enterprise Linux, Squid 2024-10-24 N/A 7.5 HIGH
A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service.
CVE-2023-46848 2 Redhat, Squid-cache 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more 2024-09-16 N/A 7.5 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 2024-09-16 N/A 7.5 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-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2024-09-16 N/A 5.3 MEDIUM
SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems.
CVE-2024-23638 1 Squid-cache 1 Squid 2024-04-25 N/A 6.5 MEDIUM
Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6 is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. 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. As a workaround, prevent access to Cache Manager using Squid's main access control: `http_access deny manager`.
CVE-2023-49285 1 Squid-cache 1 Squid 2024-02-28 N/A 7.5 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.
