CVE-2004-0189 1 Squid 1 Squid 2025-04-03 7.5 HIGH N/A
The "%xx" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL ("%00") character, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists.
CVE-2005-3258 1 Squid 1 Squid 2025-04-03 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-2002-0713 1 Squid 1 Squid 2025-04-03 7.5 HIGH N/A
Buffer overflows in Squid before 2.4.STABLE6 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code (1) via the MSNT auth helper (msnt_auth) when using denyusers or allowusers files, (2) via the gopher client, or (3) via the FTP server directory listing parser when HTML output is generated.
CVE-2005-1711 3 Clam Anti-virus, Gibraltar, Squid 3 Clamav, Gibraltar Firewall, Squid 2025-04-03 7.5 HIGH 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-2002-0069 2 Redhat, Squid 2 Linux, Squid 2025-04-03 2.6 LOW N/A
Memory leak in SNMP in Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service.
CVE-2005-0094 1 Squid 1 Squid 2025-04-03 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-2002-0715 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM 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-2004-0832 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM N/A
The (1) ntlm_fetch_string and (2) ntlm_get_string functions in Squid 2.5.6 and earlier, with NTLM authentication enabled, allow remote attackers to cause a denial of service (application crash) via an NTLMSSP packet that causes a negative value to be passed to memcpy.
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-2005-1345 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-2005-2796 1 Squid 1 Squid 2025-04-03 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-2005-0174 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-2002-0714 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-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-2005-2917 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-2005-0097 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.
CVE-2005-3322 2 Squid, Suse 2 Squid, Suse Linux 2025-04-03 5.0 MEDIUM N/A
Unspecified vulnerability in Squid on SUSE Linux 9.0 allows remote attackers to cause a denial of service (crash) via HTTPs (SSL).
