CVE-2008-1612 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-09 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-2007-1560 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-09 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 2025-04-09 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 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-2009-0478 1 Squid 1 Squid 2025-04-09 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-2005-0175 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-03 N/A
Squid 2.5 up to 2.5.STABLE7 allows remote attackers to poison the cache via an HTTP response splitting attack.
CVE-2005-0194 1 Squid 1 Squid 2025-04-03 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-2005-1345 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-03 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-2005-1711 3 Clam Anti-virus, Gibraltar, Squid 3 Clamav, Gibraltar Firewall, Squid 2025-04-03 N/A
Gibraltar Firewall 2.2 and earlier, when using the ClamAV update to 0.81 for Squid, uses a defunct ClamAV method to scan memory for viruses, which does not return an error code and prevents viruses from being detected.
CVE-2005-3322 2 Squid, Suse 2 Squid, Suse Linux 2025-04-03 N/A
Unspecified vulnerability in Squid on SUSE Linux 9.0 allows remote attackers to cause a denial of service (crash) via HTTPs (SSL).
CVE-2005-3258 1 Squid 1 Squid 2025-04-03 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-2002-0068 2 Redhat, Squid 2 Linux, Squid 2025-04-03 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-2002-0163 2 Redhat, Squid 2 Linux, Squid 2025-04-03 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.
CVE-2005-1519 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-03 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-2005-2917 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-03 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-2004-2654 1 Squid 1 Squid 2025-04-03 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-2005-0094 2 Redhat, Squid 2 Enterprise Linux, Squid 2025-04-03 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-2002-0067 2 Redhat, Squid 2 Linux, Squid 2025-04-03 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 2025-04-03 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 2025-04-03 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.
