Squid: Denial of service when using NTLM authentication

Background Squid is a full-featured Web Proxy Cache designed to run on Unix systems. It supports proxying and caching of HTTP, FTP, and other URLs, as well as SSL support, cache hierarchies, transparent caching, access control lists and many other features. Description Squid 2.5.x versions contai...

CVE-2004-0189

CVE-2004-0189 concerns a bug in the URL decoding '%xx' function in Squid 2.5.STABLE4 and earlier that can inject a NULL character into decoded URLs, causing Squid to compare only a portion of the requested URL against ACLs. This can allow bypass of url_regex-based access control lists. Public dis...

squid -- NTLM authentication denial-of-service vulnerability

A remote attacker is able to cause a denial-of-service situation, when NTLM authentication is enabled in squid. NTLM authentication uses two functions which lack correct offset checking...

Mandrake Linux Security Advisory : squid (MDKSA-2002:016-1)

Three security issues were found in the 2.x versions of the Squid proxy server up to and including 2.4.STABLE3. The first is a memory leak in the optional SNMP interface to Squid which could allow a malicious user who can send packets to the Squid SNMP port to possibly perform a Denial of Service...

Mandrake Linux Security Advisory : squid (MDKSA-2004:025)

A vulnerability was discovered in squid version 2.5.STABLE4 and earlier with the processing of %-encoded characters in a URL. If a squid configuration uses ACLs Access Control Lists, it is possible for a remote attacker to create URLs that would not be properly tested against squid's ACLs,...

Mandrake Linux Security Advisory : squid (MDKSA-2004:059)

A vulnerability exists in squid's NTLM authentication helper. This buffer overflow can be exploited by a remote attacker by sending an overly long password, thus overflowing the buffer and granting the ability to execute arbitrary code. This can only be exploited, however, if NTLM authentication ...

Mandrake Linux Security Advisory : squid (MDKSA-2001:066)

The Squid proxy server has a serious security flaw in versions 2.3.STABLE2 through 2.3.STABLE4. This problem surfaces when Squid is used in httpdaccel mode. If you configure httpaccelwithproxy off then any request to Squid is allowed. Malicious users may use your proxy to portscan remote systems,...
