Furthermore, a user could read log file content even when plugin rawlog was not enabled. </p> </description> <impact type="high"> <p> A remote attacker could supply AWStats malicious input, potentially allowing the execution of arbitrary code with the rights of the web server. He could also access raw log contents. </p> </impact> <workaround> <p> Making sure that AWStats does not run as a CGI script will avoid the issue, but we recommend that users upgrade to the latest version, which fixes these bugs. </p> </workaround> <resolution> <p> All AWStats users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=www-misc/awstats-6.3-r2"</code> <p> Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update. </p> </resolution> <references> <uri link="https://awstats.sourceforge.net/docs/awstats_changelog.txt">AWStats ChangeLog</uri> <uri link="http://www.idefense.com/application/poi/display?id=185">iDEFENSE Advisory</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0116">CAN-2005-0116</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0362">CAN-2005-0362</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0363">CAN-2005-0363</uri> </references> <metadata tag="requester" timestamp="2005-01-18T13:51:20Z"> koon </metadata> <metadata tag="submitter" timestamp="2005-01-22T01:15:21Z"> lewk </metadata> <metadata tag="bugReady" timestamp="2005-01-25T18:48:59Z"> jaervosz </metadata> </glsa>
