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-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-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-2007-1560 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-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-2005-0174 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 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-2002-2414 2 Opera Software, Squid 2 Opera, Squid 2025-04-03 4.3 MEDIUM 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-2005-2917 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
Squid 2.5.STABLE10 and earlier, while performing NTLM authentication, does not properly handle certain request sequences, which allows attackers to cause a denial of service (daemon restart).
CVE-2005-0096 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM 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).
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-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-2005-2794 1 Squid 1 Squid 2025-04-03 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-2005-0241 1 Squid 1 Squid 2025-04-03 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-2002-0068 2 Redhat, Squid 2 Linux, Squid 2025-04-03 7.5 HIGH N/A
Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.
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-2005-0173 1 Squid 1 Squid 2025-04-03 7.5 HIGH 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-2005-1345 1 Squid 1 Squid 2025-04-03 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-2005-0446 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-2005-0626 1 Squid 1 Squid 2025-04-03 2.6 LOW 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.
CVE-2005-0097 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM 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.
