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-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-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-2007-0248 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-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-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-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-2005-0094 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2005-0446 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-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-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-2005-0718 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 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-2001-1030 6 Caldera, Immunix, Mandrakesoft and 3 more 8 Openlinux Server, Immunix, Mandrake Linux and 5 more 2026-04-16 N/A
Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.
CVE-2002-0067 2 Redhat, Squid 2 Linux, Squid 2026-04-16 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-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-2004-0918 6 Gentoo, Openpkg, Redhat and 3 more 7 Linux, Openpkg, Enterprise Linux and 4 more 2026-04-16 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-2002-2414 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-2002-0715 2 Redhat, Squid 3 Enterprise Linux, Linux, Squid 2026-04-16 N/A
Vulnerability in Squid before 2.4.STABLE6 related to proxy authentication credentials may allow remote web sites to obtain the user's proxy login and password.
CVE-2005-0175 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 via an HTTP response splitting attack.
CVE-2005-0096 2 Redhat, Squid 2 Enterprise Linux, Squid 2026-04-16 N/A
Memory leak in the NTLM fakeauth_auth helper for Squid 2.5.STABLE7 and earlier allows remote attackers to cause a denial of service (memory consumption).
