1. Problem Description

        Some vulnerabilities have been reported in CUPS, which can
        be exploited by malicious people to cause a DoS (Denial of
        Service) and potentially to compromise a vulnerable system.
        
        The vulnerabilities are caused due to the use of a vulnerable
        version of Xpdf.
        
        The Common Vulnerabilities and Exposures project
        (cve.mitre.org) has assigned the names CVE-2005-3191,
        CVE-2005-3192, and CVE-2005-3193 to these issues.
