<description>
|
|
<p>The pluto IKE daemon in Libreswan, when built with NSS, allows remote
|
|
attackers to cause a Denial of Service (assertion failure and daemon
|
|
restart) via a zero DH g^x value in a KE payload in a IKE packet.
|
|
Additionally, remote attackers could cause a Denial of Service (daemon
|
|
restart) via an IKEv1 packet with (1) unassigned bits set in the IPSEC
|
|
DOI value or (2) the next payload value set to ISAKMP_NEXT_SAK.
