Vulnerability Assessment Details

RHSA-2004-133: squid

Vulnerability Assessment Summary
Check for the version of the squid packages

Detailed Explanation for this Vulnerability Assessment


An updated squid package is avaliable that fixes a security vulnerability
in
URL decoding and provides a new ACL type for protecting vulnerable clients.

Squid is a full-featured Web proxy cache.

A bug was found in the processing of %-encoded characters in a URL in
versions of Squid 2.5.STABLE4 and earlier. If a Squid configuration uses
Access Control Lists (ACLs), a remote attacker could create URLs that would
not be correctly tested against Squid's ACLs, potentially permiting clients
to access prohibited URLs.

Users of Squid should update to these erratum packages which are not
vulnerable to this issue.

In addition, these packages contain a new Access Control type, "urllogin",
which can be used to protect vulnerable Microsoft Internet Explorer clients
from accessing URLs that contain login information. Such URLs are often
used by fraudsters to trick web users into revealing valuable personal
data.

Note that the default Squid configuration does not make use of this new
access control type. You must explicitly configure Squid with ACLs that
use this new type, in accordance with your own site policies.
