There is also an error in the external_acl queue which can cause an infinite looping condition. </p> </description> <impact type="normal"> <p> An attacker could attempt to retrieve a specially crafted URI via a Squid server causing the service to crash. If an attacker could generate a sufficiently high load on the Squid services, they could cause a Denial of Service by forcing Squid into an infinite loop. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All Squid users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0247">CVE-2007-0247</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0248">CVE-2007-0248</uri> </references> <metadata tag="requester" timestamp="2007-01-22T16:59:17Z"> vorlon </metadata> <metadata tag="submitter" timestamp="2007-01-23T10:26:06Z"> hyakuhei </metadata> <metadata tag="bugReady" timestamp="2007-01-24T12:52:50Z"> hyakuhei </metadata> </glsa>
