Several independent researchers also reported errors involving the handling of HTTP headers, the mod_auth and mod_scgi modules, and the limitation of active connections. </p> </description> <impact type="normal"> <p> A remote attacker can trigger any of these vulnerabilities by sending malicious data to the server, which may lead to a crash or memory exhaustion, and potentially the execution of arbitrary code. Additionally, access-deny settings can be evaded by appending a final / to a URL. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All Lighttpd users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.16"</code> </resolution> <references> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3946">CVE-2007-3946</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3947">CVE-2007-3947</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3948">CVE-2007-3948</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3949">CVE-2007-3949</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3950">CVE-2007-3950</uri> </references> <metadata tag="requester" timestamp="Tue, 17 Jul 2007 18:07:17 +0000"> jaervosz </metadata> <metadata tag="submitter" timestamp="Sun, 12 Aug 2007 21:28:06 +0000"> falco </metadata> <metadata tag="bugReady" timestamp="Wed, 15 Aug 2007 05:43:43 +0000"> jaervosz </metadata> </glsa>
