CVE-2007-6239 1 Squid 1 Squid Web Proxy Cache 2025-04-09 5.0 MEDIUM N/A
The "cache update reply processing" functionality in Squid 2.x before 2.6.STABLE17 and Squid 3.0 allows remote attackers to cause a denial of service (crash) via unknown vectors related to HTTP headers and an Array memory leak during requests for cached objects.
CVE-2009-0801 1 Squid 1 Squid Web Proxy Cache 2025-04-09 5.4 MEDIUM N/A
Squid, when transparent interception mode is enabled, uses the HTTP Host header to determine the remote endpoint, which allows remote attackers to bypass access controls for Flash, Java, Silverlight, and probably other technologies, and possibly communicate with restricted intranet sites, via a crafted web page that causes a client to send HTTP requests with a modified Host header.
CVE-2007-1560 1 Squid 1 Squid 2025-04-09 5.0 MEDIUM N/A
The clientProcessRequest() function in src/client_side.c in Squid 2.6 before 2.6.STABLE12 allows remote attackers to cause a denial of service (daemon crash) via crafted TRACE requests that trigger an assertion error.
CVE-2009-0478 1 Squid 1 Squid 2025-04-09 5.0 MEDIUM N/A
Squid 2.7 to 2.7.STABLE5, 3.0 to 3.0.STABLE12, and 3.1 to 3.1.0.4 allows remote attackers to cause a denial of service via an HTTP request with an invalid version number, which triggers a reachable assertion in (1) HttpMsg.c and (2) HttpStatusLine.c.
CVE-2008-1612 1 Squid 1 Squid 2025-04-09 4.3 MEDIUM N/A
The arrayShrink function (lib/Array.c) in Squid 2.6.STABLE17 allows attackers to cause a denial of service (process exit) via unknown vectors that cause an array to shrink to 0 entries, which triggers an assert error. NOTE: this issue is due to an incorrect fix for CVE-2007-6239.
CVE-2007-0248 1 Squid 1 Squid 2025-04-09 5.0 MEDIUM N/A
The aclMatchExternal function in Squid before 2.6.STABLE7 allows remote attackers to cause a denial of service (crash) by causing an external_acl queue overload, which triggers an infinite loop.
CVE-2007-0247 1 Squid 1 Squid 2025-04-09 5.0 MEDIUM N/A
squid/src/ftp.c in Squid before 2.6.STABLE7 allows remote FTP servers to cause a denial of service (core dump) via crafted FTP directory listing responses, possibly related to the (1) ftpListingFinish and (2) ftpHtmlifyListEntry functions.
CVE-2004-0832 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
The (1) ntlm_fetch_string and (2) ntlm_get_string functions in Squid 2.5.6 and earlier, with NTLM authentication enabled, allow remote attackers to cause a denial of service (application crash) via an NTLMSSP packet that causes a negative value to be passed to memcpy.
CVE-2005-0175 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
Squid 2.5 up to 2.5.STABLE7 allows remote attackers to poison the cache via an HTTP response splitting attack.
CVE-2005-0718 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
Squid 2.5.STABLE7 and earlier allows remote attackers to cause a denial of service (segmentation fault) by aborting the connection during a (1) PUT or (2) POST request, which causes Squid to access previously freed memory.
CVE-2001-0843 1 Squid 1 Squid Web Proxy 2025-04-03 5.0 MEDIUM N/A
Squid proxy server 2.4 and earlier allows remote attackers to cause a denial of service (crash) via a mkdir-only FTP PUT request.
CVE-2002-0714 1 Squid 1 Squid 2025-04-03 7.5 HIGH N/A
FTP proxy in Squid before 2.4.STABLE6 does not compare the IP addresses of control and data connections with the FTP server, which allows remote attackers to bypass firewall rules or spoof FTP server responses.
CVE-2004-0189 1 Squid 1 Squid 2025-04-03 7.5 HIGH N/A
The "%xx" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL ("%00") character, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists.
CVE-2004-0918 6 Gentoo, Openpkg, Redhat and 3 more 6 Linux, Openpkg, Fedora Core and 3 more 2025-04-03 5.0 MEDIUM N/A
The asn_parse_header function (asn1.c) in the SNMP module for Squid Web Proxy Cache before 2.4.STABLE7 allows remote attackers to cause a denial of service (server restart) via certain SNMP packets with negative length fields that trigger a memory allocation error.
CVE-2002-0069 2 Redhat, Squid 2 Linux, Squid 2025-04-03 2.6 LOW N/A
Memory leak in SNMP in Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service.
CVE-2005-0446 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
Squid 2.5.STABLE8 and earlier allows remote attackers to cause a denial of service (crash) via certain DNS responses regarding (1) Fully Qualified Domain Names (FQDN) in fqdncache.c or (2) IP addresses in ipcache.c, which trigger an assertion failure.
CVE-2004-2654 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
The clientAbortBody function in client_side.c in Squid Web Proxy Cache before 2.6 STABLE6 allows remote attackers to cause a denial of service (segmentation fault) via unspecified vectors that trigger a null dereference. NOTE: in a followup advisory, a researcher claimed that the issue was a buffer overflow that was not fixed in STABLE6. However, the vendor's bug report clearly shows that the researcher later retracted this claim, because the tested product was actually STABLE5.
CVE-2005-1519 1 Squid 1 Squid 2025-04-03 6.4 MEDIUM N/A
Squid 2.5 STABLE9 and earlier, when the DNS client port is unfiltered and the environment does not prevent IP spoofing, allows remote attackers to spoof DNS lookups.
CVE-2002-0067 2 Redhat, Squid 2 Linux, Squid 2025-04-03 7.5 HIGH N/A
Squid 2.4 STABLE3 and earlier does not properly disable HTCP, even when "htcp_port 0" is specified in squid.conf, which could allow remote attackers to bypass intended access restrictions.
CVE-2002-0163 1 Squid 1 Squid 2025-04-03 7.5 HIGH N/A
Heap-based buffer overflow in Squid before 2.4 STABLE4, and Squid 2.5 and 2.6 until March 12, 2002 distributions, allows remote attackers to cause a denial of service, and possibly execute arbitrary code, via compressed DNS responses.
