CVE-2005-0446 1 Squid 1 Squid 2017-10-10 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-2004-0189 1 Squid 1 Squid 2017-10-09 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-2001-1030 6 Caldera, Immunix, Mandrakesoft and 3 more 8 Openlinux Server, Immunix, Mandrake Linux and 5 more 2017-10-09 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-2001-0843 1 Squid 1 Squid Web Proxy 2017-10-09 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-2007-6239 1 Squid 1 Squid Web Proxy Cache 2017-09-28 5.0 MEDIUM 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 2017-07-28 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 2017-07-28 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-2005-0194 1 Squid 1 Squid 2016-10-17 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-2002-2414 2 Opera Software, Squid 2 Opera, Squid 2016-10-17 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-2002-0713 1 Squid 1 Squid 2016-10-17 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-2002-0715 1 Squid 1 Squid 2016-10-17 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-2002-0714 1 Squid 1 Squid 2016-10-17 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-2002-0163 1 Squid 1 Squid 2016-10-17 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-2002-0068 2 Redhat, Squid 2 Linux, Squid 2016-10-17 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-2002-0069 2 Redhat, Squid 2 Linux, Squid 2016-10-17 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-2002-0067 2 Redhat, Squid 2 Linux, Squid 2016-10-17 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-2005-3258 1 Squid 1 Squid 2011-03-07 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-2009-0801 1 Squid 1 Squid Web Proxy Cache 2009-06-17 5.4 MEDIUM 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-2005-3322 2 Squid, Suse 2 Squid, Suse Linux 2008-09-10 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-2005-1711 3 Clam Anti-virus, Gibraltar, Squid 3 Clamav, Gibraltar Firewall, Squid 2008-09-05 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.
