CVE-2009-0478 1 Squid 1 Squid 2023-12-10 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-2009-0801 1 Squid 1 Squid Web Proxy Cache 2023-12-10 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-2008-1612 1 Squid 1 Squid 2023-12-10 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-2007-0247 1 Squid 1 Squid 2023-12-10 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-2007-1560 1 Squid 1 Squid 2023-12-10 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-2007-6239 1 Squid 1 Squid Web Proxy Cache 2023-12-10 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-2007-0248 1 Squid 1 Squid 2023-12-10 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-2004-2654 1 Squid 1 Squid 2023-12-10 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-2005-2796 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
The sslConnectTimeout function in ssl.c for Squid 2.5.STABLE10 and earlier allows remote attackers to cause a denial of service (segmentation fault) via certain crafted requests.
CVE-2005-0175 1 Squid 1 Squid 2023-12-10 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-2005-3258 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
The rfc1738_do_escape function in ftp.c for Squid 2.5 STABLE11 and earlier allows remote FTP servers to cause a denial of service (segmentation fault) via certain "odd" responses.
CVE-2005-0241 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
The httpProcessReplyHeader function in http.c for Squid 2.5-STABLE7 and earlier does not properly set the debug context when it is handling "oversized" HTTP reply headers, which might allow remote attackers to poison the cache or bypass access controls based on header size.
CVE-2005-0446 1 Squid 1 Squid 2023-12-10 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-2005-2794 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
store.c in Squid 2.5.STABLE10 and earlier allows remote attackers to cause a denial of service (crash) via certain aborted requests that trigger an assert error related to STORE_PENDING.
CVE-2005-1345 1 Squid 1 Squid 2023-12-10 7.5 HIGH N/A
Squid 2.5.STABLE9 and earlier does not trigger a fatal error when it identifies missing or invalid ACLs in the http_access configuration, which could lead to less restrictive ACLs than intended by the administrator.
CVE-2005-0094 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
Buffer overflow in the gopherToHTML function in the Gopher reply parser for Squid 2.5.STABLE7 and earlier allows remote malicious Gopher servers to cause a denial of service (crash) via crafted responses.
CVE-2005-0174 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
Squid 2.5 up to 2.5.STABLE7 allows remote attackers to poison the cache or conduct certain attacks via headers that do not follow the HTTP specification, including (1) multiple Content-Length headers, (2) carriage return (CR) characters that are not part of a CRLF pair, and (3) header names containing whitespace characters.
CVE-2004-0918 6 Gentoo, Openpkg, Redhat and 3 more 6 Linux, Openpkg, Fedora Core and 3 more 2023-12-10 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-2005-0095 1 Squid 1 Squid 2023-12-10 5.0 MEDIUM N/A
The WCCP message parsing code in Squid 2.5.STABLE7 and earlier allows remote attackers to cause a denial of service (crash) via malformed WCCP messages with source addresses that are spoofed to reference Squid's home router and invalid WCCP_I_SEE_YOU cache numbers.
CVE-2005-0194 1 Squid 1 Squid 2023-12-10 10.0 HIGH N/A
Squid 2.5, when processing the configuration file, parses empty Access Control Lists (ACLs), including proxy_auth ACLs without defined auth schemes, in a way that effectively removes arguments, which could allow remote attackers to bypass intended ACLs if the administrator ignores the parser warnings.
