"The remote host is running a version of Juniper NetScreen VPN client
that is affected by multiple buffer overflow vulnerabilities :

  - The IKE VPN service listening on UDP port 62514 is
    vulnerable to a stack overflow vulnerability that can be
    triggered by sending specially crafted packets.
    (CVE-2009-1943)

  - spdedit.exe has a flaw in parsing specially crafted SPD
    files that can be utilized to trigger a stack overflow.
    (CVE-2009-3861)

Successful exploitation of either of these vulnerabilities could allow a
remote attacker to execute arbitrary code on the host."
