<background>
|
|
<p>Firewalld provides a dynamically managed firewall with support for
|
|
network/firewall zones to define the trust level of network connections
|
|
or interfaces.

<description>
|
|
<p>A flaw in Firewalld allows any locally logged in user to tamper with or
|
|
change firewall settings. This is due to how Firewalld handles
|
|
authentication via polkit which is not properly applied to 5 particular
|
|
functions to include: addPassthrough, removePassthrough, addEntry,
|
|
removeEntry, and setEntries.
|
|
</p>

|
|
<impact type="normal">
|
|
<p>A local attacker could tamper or change firewall settings leading to the
|
|
additional exposure of systems to include unauthorized remote access.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All Firewalld users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-firewall/firewalld-0.4.3.3"
|
|
</code>
