|
<p>
|
|
The OpenVPN client contains a format string bug in the handling of
|
|
the foreign_option in options.c. Furthermore, when the OpenVPN server
|
|
runs in TCP mode, it may dereference a NULL pointer under specific
|
|
error conditions.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could setup a malicious OpenVPN server and trick
|
|
the user into connecting to it, potentially executing arbitrary code on
|
|
the client's computer. A remote attacker could also exploit the NULL
|
|
dereference issue by sending specific packets to an OpenVPN server
|
|
running in TCP mode, resulting in a Denial of Service condition.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not use "pull" or "client" options in the OpenVPN client
|
|
configuration file, and use UDP mode for the OpenVPN server.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All OpenVPN users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/openvpn-2.0.4"</code>
|
|
</resolution>
