The vulnerabilities are exploitable via the network when CUPS is sharing printers remotely. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All CUPS users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=net-print/cups-1.2.12-r7"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0047">CVE-2008-0047</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0053">CVE-2008-0053</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0882">CVE-2008-0882</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1373">CVE-2008-1373</uri> </references> <metadata tag="requester" timestamp="2008-03-08T16:37:44Z"> rbu </metadata> <metadata tag="submitter" timestamp="2008-03-18T13:25:31Z"> rbu </metadata> <metadata tag="bugReady" timestamp="2008-04-01T19:15:08Z"> rbu </metadata> </glsa>
