IPsec-Tools is a port of KAME's implementation of the IPsec utilities.
|
|
It contains a collection of network monitoring tools, including racoon,
|
|
ping, and ping6.

<description>
|
|
<p>
|
|
The isakmp_info_recv() function in src/racoon/isakmp_inf.c does not
|
|
always check that DELETE (ISAKMP_NPTYPE_D) and NOTIFY (ISAKMP_NPTYPE_N)
|
|
packets are encrypted.
|
|
</p>
|

|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could send a specially crafted IPsec message to one
|
|
of the two peers during the beginning of phase 1, resulting in the
|
|
termination of the IPsec exchange.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All IPsec-Tools users should upgrade to the latest version:
|

</p>
|
|
<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.6.7"</code>
