CVE-2008-1612 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-23 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-2009-0801 1 Squid 1 Squid Web Proxy Cache 2026-04-23 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-2009-0478 1 Squid 1 Squid 2026-04-23 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-2007-0248 1 Squid 1 Squid 2026-04-23 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-2007-1560 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-23 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-2007-0247 1 Squid 1 Squid 2026-04-23 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-2007-6239 2 Redhat, Squid 2 Enterprise Linux, Squid Web Proxy Cache 2026-04-23 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-2005-0174 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-0097 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 N/A
The NTLM component in Squid 2.5.STABLE7 and earlier allows remote attackers to cause a denial of service (crash) via a malformed NTLM type 3 message that triggers a NULL dereference.
CVE-2004-2654 1 Squid 1 Squid 2026-04-16 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-2002-2414 2 Opera Software, Squid 2 Opera, Squid 2026-04-16 N/A
Opera 6.0.3, when using Squid 2.4 for HTTPS proxying, does not properly handle when accepting a non-global certificate authority (CA) certificate from a site and establishing a subsequent HTTPS connection, which allows remote attackers to cause a denial of service (crash).
CVE-2005-0194 1 Squid 1 Squid 2026-04-16 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.
CVE-2005-0446 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-3258 1 Squid 1 Squid 2026-04-16 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-2002-0714 2 Redhat, Squid 3 Enterprise Linux, Linux, Squid 2026-04-16 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-2005-1519 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-0095 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-0173 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 N/A
squid_ldap_auth in Squid 2.5 and earlier allows remote authenticated users to bypass username-based Access Control Lists (ACLs) via a username with a space at the beginning or end, which is ignored by the LDAP server.
CVE-2005-0241 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-0626 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 N/A
Race condition in Squid 2.5.STABLE7 to 2.5.STABLE9, when using the Netscape Set-Cookie recommendations for handling cookies in caches, may cause Set-Cookie headers to be sent to other users, which allows attackers to steal the related cookies.
