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

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandrake Linux host is missing a security update.

Description :

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, potentially allowing clients to access URLs that
would otherwise be disallowed.

As well, the provided packages for Mandrake Linux 9.2 and 9.1 include
a new Access Control type called 'urllogin' which can be used to
protect vulnerable Microsoft Internet Explorer clients from accessing
URLs that contain login information. While this Access Control type is
available, it is not used in the default configuration.

The updated packages are patched to protect against these
vulnerabilities.
