<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>

# emerge --sync
|
