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-2001-1030 6 Caldera, Immunix, Mandrakesoft and 3 more 8 Openlinux Server, Immunix, Mandrake Linux and 5 more 2025-04-03 7.5 HIGH 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-2005-1519 1 Squid 1 Squid 2025-04-03 6.4 MEDIUM 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-2005-0174 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-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-2001-0843 1 Squid 1 Squid Web Proxy 2025-04-03 5.0 MEDIUM N/A
Squid proxy server 2.4 and earlier allows remote attackers to cause a denial of service (crash) via a mkdir-only FTP PUT request.
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-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-2005-3322 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).
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-2005-0194 1 Squid 1 Squid 2025-04-03 10.0 HIGH 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-2002-0163 1 Squid 1 Squid 2025-04-03 7.5 HIGH 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-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-2005-0097 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-2005-0718 1 Squid 1 Squid 2025-04-03 5.0 MEDIUM 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-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-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-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-2005-0241 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-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.
