3. Problem description:

Squid is a full-featured Web proxy cache.
A bug was found in the way Squid handles FQDN lookups. It was possible to crash the Squid server by sending a carefully crafted DNS response to an FQDN lookup. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0446 to this issue.
Users of squid should upgrade to this updated package, which contains a backported patch, and is not vulnerable to this issue.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
