Mandrake Linux Security Advisory : squid (MDKSA-2004:025)
High Nessus Plugin ID 14124
SynopsisThe remote Mandrake Linux host is missing a security update.
DescriptionA 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.
SolutionUpdate the affected squid package.
