    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:
    
        up2date
