+ <background>
+ <p>Fail2ban is a tool for parsing log files and banning IP addresses which
+ show suspicious behavior.
+ </p>
+ </background>
+ <description>
+ <p>Multiple vulnerabilities have been discovered in Fail2ban. Please review
+ the CVE identifiers referenced below for details.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>A remote attacker could send a crafted URL to a web site which, when
+ parsed by Fail2ban, would deny a specific IP address. Also, errors in
+ regular expressions within certain filters can cause arbitrary IP
+ addresses to be banned. Furthermore, a local attacker could perform
+ symlink attacks to overwrite arbitrary files with the privileges of the
+ user running the application.
+ </p>
+ </impact>
+ <workaround>
+ <p>There is no known workaround at this time.</p>
+ </workaround>
+ <resolution>
+ <p>All Fail2ban users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-analyzer/fail2ban-0.8.12
+ </code>
