IPV4_RANGE causes isakmpd crash

Hi,

I have found that isakmpd can crash when it is establishing a connexion with a host which use IPV4_RANGE in Phase 2 (for example ZyWall 10).

The problem occurs in the function ipsec_set_network of the ipsec.c file.

In each switch(id) of the function there is no case IPSEC_ID_IPV4_RANGE. So, when the execution leave the switch, the isa variable is not properly filled. And the following memcpy crash because of null pointer.

Same thing can appear with Phase 2 ID :
- IPSEC_ID_IPV6_RANGE

• IPSEC_ID_DER_ASN1_DN
• IPSEC_ID_DER_ASN1_GN
• IPSEC_ID_KEY_ID

Hope this can help.
